MC literally cried at him to just leave her alone after he screws sh*t up by doing something she never asked him to do and acted like he was wronged afterwards, and not even 10 chapters later does he poke into her affairs again, like seriously get the hint bruh

I find the situation that the MC doesn't like the protagonist ridiculous. Not going to go to all the reasons, but I'll go into one that annoyed me a lot. At one point in the story, the MC goes into a motel with an old bald guy in order to earn extra cash due to her situation of buying food everyday for a Sylvia who she wishes to be friends with. The author creates a situation where it looks more dire than it seems, but she really only shows her power in the motel room to a bunch of scientist to earn money. Now leading up to this point the protagonist actually sees her entering in the motel with an old man and came out exhausted and has an envelope of cash, what kind of misunderstanding does that lead up to you may ask? Well apparently the MC was too oblivious to see what it can insinuate and continues making it look worse by saying that she does it for the money or she likes doing it without even realizing what it looks like. He eventually came into her house later and saw her financial situation, which is not good. So he knows her financial situation isn't good, she is sleeping around with men for money, and continues being a bread shuttle for Sylvia, which btw doesn't even consider her a friend at the time. He eventually intervened with the bread shuttle situation and when she finds out she practically freaked out and starting hating the protagonist. Yes it was later revealed that she is basically trying to be friends with Sylvia to survive, but it's not like he would know? I don't understand all the hate with the protagonists when it's mainly simple misunderstanding that she creates due to the excuse of being too oblivious to see herself looking like a bread shuttle or a person that sleeps around for money. I hope the situation gets better in the future rather than the author spewing more random reason for the MC to hate the protagonist even more.

Basically, we find out that Scarlett, the MC, was actually a taboo homunculus who was made with emotions during experiments to recreate the Witch of Wrath, through that fragment of the witch's heart, as a weapon, but one of her experimentors (her now- guardian) took pity on her and gave her an identity after she burned the lab down. Since she endured a boatload of torture and healing, her natural healing was reduced and MC, along with Siwoo and Sylvia find out that MC has only 3 years left to live. We also find out that the original Scarlett had battled the ego of the Witch, who wanted to burn the whole world down, and died by burning herself to death, which was the original reason why Siwoo was late as he was stopping the fire. Sylvia truly becomes friends with Scarlett, Siwoo becomes more resolved to grow stronger and he ends up stronger than the original story. Scarlett constantly battles with the ego of the Witch of Wrath to prevent herself from incinerating her friends and also realizes that the original Scarlett's ego is still alive and helped repress the ego of the Witch.

After a sh*t ton happens, Scarlett who became a normal human but also has the egos of the pacified Witch of Wrath, Evangeline, and the ego of the original Scarlett. Siwoo confesses his love, Scarlett rejects him, but realizing his feelings would linger, she tells him to keep confessing to her so that she could reject him and that he could get over her.... which doesnt happen after 99 rejections. Evangeline takes over the body for a moment, and reveals that Scarlett's heart had always been racing whenever she was confessed to, but she didnt realize that it was because she liked him back. After attending an academy reunion, Scarlett gets super drunk and Siwoo takes her home, but they end up at a motel instead and Scarlett drunkenly kisses him. This is the part that some people might dislike, but basically, Siwoo is unable to hold back and gives drunk Scarlett a code word to tell him to stop which she doesnt use, and they very make love under dubious consent. The morning after, Scarlett realizes what happened and while Siwoo contemplates turning himself in for r*pe, Scarlett not wanting to get him in trouble tells him to confess to her one more time (the 100th time) and she accepts him and they ACTUALLY start passionately making love.

Maybe a bit too much though, cus now the plot is about how they literally go at it every night and Scarlett wakes up increasingly later due to the fatigue, so they decide to abstain for every 3 days instead of every day. While Siwoo desperately holds himself back, Evangeline and original Scarlett come up with a plan to f*ck him, and Evangeline basically presents herself, in Scarlett's body, as a m*sturbation toy. She passes out from it because shes used to pain but not pleasure, and original Scarlett is suddenly in control, and uh yeah she gets piped.

Scarlett, feeling exhausted from Evangeline and og Scarlett's shenanigans, decides to extend the abstinence to a week, under the guise of doing normal couple stuff that ISNT f*ckING. Siwoo desperately holds himself back, but at the 6th day on Saturday, they watch a movie together but Scarlett unknowingly keeps brushing up against Siwoo and he unleashes the beast... probably. The chapter ended when Scarlett realized he was pent up. Netflix and chill is probably happening, but that's for ch 403 and thats not released yet.

First ~20 chapters: The story feels like your average academy novel, where the main character and the few characters she interacts with are all annoying. The MC voluntarily becomes a bread shuttle/errand girl for the popular type girl/main heroine from the original story the MC isekaid into. She initially seems dumb for acting like this, BUT

Chapter 31 explains that the MC was actually doing this on purpose. In fact, most of the annoyances from the characters in previous chapters start getting explained after this, and honestly, by the latest chapters it's hard to really hate any of them any more (your anger gets diverted towards many of the other villainous characters that get introduced later).

Chapter 38: This is when the story's first major action arc occurs. The story has regular action scenes and plot advances/twists from this point forward.

Chapter 50: The full background setting of the fantasy world gets revealed here. And it was very surprising, because it reveals a world with a much larger scale than I expected. It made me realize that the story could go well past the academy setting at some point, with characters having to go to different places around the world to fix problems.

Chapter 78: This chapter is the beginning of one of my favorite arcs. The writing here was particularly good, and really gets you emotionally invested in what happens. The story already had dark scenes before this, but things get particularly bad from this moment on.

except in early story when the monster attack the gymnasium

So... about that romance tag. I feel like it's false advertising. From start to finish the only romance with MC is one sided unspoken love from other characters toward MC. MC herself never considers a single person in a romantic way even in the slightest.

And then we have the gender bender. Honestly I really like gender bender stories, but this one really have no real reason to be one because it is barely relevant in the plot and MC also never really goes through any related development. Their mentality is from start to finish completely unchanged.

He's also the love interest. Go, Si Woo, Go!
