It is later revealed in the novel that Cheng Lang usually screws over similar plots before using "the butterfly effect" of helping the protagonist focus on their "career line". Due to his unconventional methods, he was selected as an attempt to save the world because it kept collapsing due to the protagonist shou committing su*cide which resets the worldline and the world couldn't function and move on...

He already planned from the start to help the ab*sed protagonist, Shen Huaiyu, start a career for his own good. He also predicted that with the personalities of the protagonist top and bottom, their roles would reverse in the end (as Lu Chengxuan would make many enemies due to his arrogance), leading to a "transfer of luck" (the novel explains the world balance phenomenon well - as long as one protagonist is a president and the other relies on the president, then the ending would meet the world's criteria for the intended "ending"). The main character doing business was born from his care and concern for Shen Huaiyu. He became more desperate when Shen Huaiyu was r*ped, and he rushed to secure Shen Huaiyu's powerful position (and also because the novel plot took around 3 years so he knew he couldn't take his time to solve the plot).

Although the plot goes "astray", the system doesn't stop Cheng Lang because his way of befriending and supporting the protagonist stabilizes the protagonist's mental health (hence, saving the world from collapsing again) - the MC is a good friend who gives helpful life advice to Shen Huaiyu, helps him get back his inheritance from relatives that took advantage of him, and takes him to travel to broaden his horizons. MC's friendship helped the protagonist develop more confidence, self-esteem and overall character growth

1. 1. Meng Tingye

• • original bad end = substitute cannon fodder due to having similar voice to the White Moonlight. Punished by the protagonist top.

• • With Cheng Lang's interference: He's tsundere lol - hot-tempered, but has a soft-heart.

• • He likes singing Rock and Roll at the bar because he shines with the crowd's enthusiasm. Cheng Lang encourages him to pursue his dreams in a music career.

• • He joined a talent show, but gets screwed over because he didn't want to sign a contract with unfair conditions.

• • Cheng Lang helps by using the publicity (for his own benefit, and to pave the way for Meng Tianye to have exposure) and uses connections so that Meng Tianye gets a favorable record deal. Meng Tianye is grateful and as a gesture of friendship, he is happy to write songs and do promotional videos for MC's brand.

• • Finally, from the "variety show" episode, we know he will do well and he is truly happy - he is passionate and whenever finds inspiration he'll write songs.

1. 1. Jin Huaiyuan

• • original bad end - vicious criminal cannon fodder senior who screws over Shen Huaiyi and ends up in jail? (I can't recall details)

• • Cheng Lang figures out the darker truth beneath the text that paints him as a villain. This senior is very good - measured, good at reading the room and bringing up the atmosphere, and can cheer others up. He hits it off with Shen Huaiyi (as they both have gentle and generous personalities).

• • He's a really good guy with a talent for storytelling of his adventures as an archeological grad student working with cultural relics. With Cheng Lang's suggestion, he publishes his adventures online and they are well received - he even wrote a fictional book based off Cheng Lang asking him "what would you do if this happened to you..." and he was surprised how vivid and realistic the plot that occurred to him was (turns out it's because he lived it before...)

• • Cheng Lang adapts a drama based on his original story because he felt it would be a pity if no one knew the truth behind the tragic and unjust life he had lived (although the main character involved is unaware). The story itself was beautiful because Jin Huaiyuan subconciously wrote a happy ending where, after the protagonist infiltrates the criminal organization of tomb raiders and brings them to justice, he discovers his parents (who were stabbed) waking up from a coma...

• • In reality, Cheng Lang's interference and butterfly effect prevented Jin Huaiyuan's from losing his parents. (A plot twist Cheng Lang discovered and kept secret to himself... you, the reader, would not have known until he brings up adapting Jin Huaiyuan's novel into a web drama later on in the novel LOL)

1. 1. Cheng Yan & Zhao Chenxu
      • • Bad end: they never intersected in the original plot. Zhao Chenxu tastes the tea Shen Huaiyu made and liked it, thus developing an interest in him. He realizes Shen Huaiyu was being held captive against his will so he tries to help him, but ends up bankrupt from Lu Chengxuan's schemes and was forced
          into business marriage with him.
      • • Cheng Lang met Cheng Yan coincidentally because Cheng Yan was running a photography studio and Cheng Lang rented an outfit for Shen Huaiyu to try on for social media views LOL
      • • Later, he buys the photography studio Cheng Yan owns to convert to an office space. Cheng Yan gave him a discount because he likes him and is reluctant to "return to run the family business".
      • • Cheng Yan is a silly and honest person, and legit said to Cheng Lang "I wished I had a younger brother to inherit the business" - turns out he does LOLOL At first, the world thought it was Cheng Lang, but the paternity tests proved that Cheng Lang was switched with somebody else - that is, Zhao Chenxu, the son of the richest man. Cheng Yan is a decent person, so he told his mother what she did was wrong, and insisted on giving assets to protect and compensate Zhao Chenxu (as he is worried about Zhao Chenxu and Cheng Lang).
      • • Zhao Chenxu cried and told MC he will never appear again (because he read bloody plots of switch-at-birth stories and felt it was unfair he lived a life that MC deserved from birth). Cheng Lang doesn't really mind because he doesn't belong to the world and the identity isn't truly his, so he convinces Zhao Chenxu to stay and straight up confesses he never planned to inherit the family business and wants to live his own life (because he knew he has to leave when the plot is complete).

1. 1. The only cannon fodder MC doesn't help, but chooses to use is Lu Chengxuan's vindictive illegitimate brother. This guy has bad tastes - he had the idea to blackmail Lu Chengxuan's mom, so Cheng Lang doesn't stop him, knowing that the illegitimate son will cause the downfall of the Lu Group. He also knew Lu Chengxuan wouldn't recover from losing everything because he had always lived a smooth life as a second-generation and doesn't know when to "bend" or be humble...

Qin Mu, the White Moonlight. When Cheng Lang first sees him, he appreciates his looks LOL

It turns out he awakened self-awareness when the world kept resetting. He initially developed an interest in MC as MC's witty remarks attracted his attention. However, he starts pursuing MC romantically (and aggressively heehee) after MC saved him from a car accident and he thought MC was in danger due to people targeting him (when MC's car was chased).

He breaks the stereotypes because ~ he wasn't good at s*x the first time they slept together LOL

• • Cheng Lang even asked him about it and Qin Mu said he didn't prepare in advance because he didn't expect Cheng Lang would agree to sleep with him so easily LOLOL.

• • Later, he studies and prepares in advance. MC was dumbfounded and amazed ML scattered rose petals and formed a heart shape on the bed LOL. Although there were candles everywhere and MC was concerned the villa might burn down HAHAHA (MC asked about the leftover candles and ML gave it to him to use at the milk tea store, because ML felt territorial and wanted others to see that they are connected LOL XD).

• • Other romantic gestures - he fulfills his promise of feeding Cheng Lang meals (as he wakes up early to cook no matter what). Upon getting to know him more, cooking is his love language. His parents divorce left a psychological shadow, and when his mom took him to a psychologist she understood they needed to spend more time together so she bonded with her son through cooking. Therefore, he grew up being the ideal husband material~

His clinginess is due to insecurity (due to his father cheating on his mother), so he was jealous of the men around MC. Cheng Lang knew it would be best to integrate him into his friend circle when they started dating.

When MC forgot to call him for half a month, they have a healthy conversation about it!!! Even ML apologized and promised to call (he knew he himself is guilty and was angry by himself LOL).

He even told MC he can be easily coaxed - so cute! No wonder why MC thinks of him as an adorable snow leopard that sometimes bites its own tail... meanwhile MC's friends are like, "aren't snow leopards carnivores??" LOL

• • Cheng Lang asked Qin Mu why he likes him and Qin Mu said he "felt real". Cheng Lang's blood ran cold... because this complicates the relationship.

• • According to Cheng Lang's experience, Qin Mu is a bug and might be eliminated ("reset factory settings") by the world's consciousness. The car accident (where the brakes broke) was arranged by the world to eliminate the bug that should have disappeared from the plot.

• • Cheng Lang doubted Qin Mu's sincerity and thought Qin Mu subconscious survival instinct recognized that Cheng Lang, a transmigrator, is the only one who can save him from being destroyed... so he thinks Qin Mu subconsciously mistook his own need to stick to him for survival as "love"

• • From the way I see it, Cheng Lang is able to understand other people's emotions, but is oblivious/ignores his own. He needed to come up with an excuse to take Qin Mu away and thought "preventing his existence from being erased" is sufficient reason to take Qin Mu back and train him as a fellow task transmigrator, instead of just admitting he fell in love with him and couldn't bear to leave him behind LOL

• • And like, anyone would fall in love with Qin Mu who is willing to give everything to the one he loves.

• • (Lu Chengxuan, in contrast, is stingy. Cheng Lang made a good point when he was analyzing transactional relationships, and Lu Chengxuan taking advantage of Shen Huaiyu in many ugly ways)

1. 1. Senxi Milk Tea/Forest Milk Tea business made sense.
      1. 1. MC knew the protagonist shou is very talented due to his good upbringing. He coincidentally met classmates talking about the shopkeeper selling their failed boba shop so it occurred to him to open a student-friendly milk tea cafe with his buddy where students can study.
      1. 1. He makes it trendy on social media because he knows it will appeal to the student/youth population (later on, his demographic audience is leverage that helps him negotiate with No. 1 Milk Tea franchise LOL)
      1. 1. Shen Huaiyu grew as a person - he developed his own goals, dreams and aspirations and found comfort through the healthy hobby of developing and making tea/tea paste which was already part of his default character setting.
      1. 1. Since MC repeatedly treats him as an equal partner and trains him, it made sense MC intended to pass the business to him when the plot ends.
      1. 1. MC also accompanied Shen Huaiyu in reaching out to good friends of his parents, because MC understood it's important to expand Shen Huaiyu's social circle and maintain a good network. (This again, caused the butterfly effect that saved Jin Huaiyuan's parents).

1. 1. Crosstalk
      1. 1. MC is witty and energetic. Making comebacks is aligned with his character. Doing crosstalk over singing happened naturally, and maybe he intended it so that he doesn't conflict with Meng Tianye (who is a talented singer).
      1. 1. MC also argued his way to help Shen Huaiyu get money back from scheming relatives.
      1. 1. MC is able to defend his friends due to his gift of gab.
      1. 1. Therefore, being known for crosstalk/ability and skill to actively engage with people and make them laugh isn't out of place considering he is an experience transmigrator who is charming, smart, cunning and capable of manipulating situations in his favour/interests.
      1. 1. It also paved the way towards his celebrity status LOL

1. 1. Music/entertainment
      1. 1. It helped him understand and help Meng Tianye further develop his career.
      1. 1. MC is good at marketing the business he started with Shen Huaiyu, and he, himself, becomes an influencer/ internet celebrity due to his poisonous tongue LOL so it made sense he appeared on the variety show he was sponsoring with Shen Huaiyu
      1. 1. Him dabbling in showbiz led to endorsing a drama adapted from Jin Huaiyuan's book
