The letter describes what will happen and the MC is just ignoring it, even after confirming that the things written about are in fact happening. His "friend" just got into a ducking coma and the MC was lamenting ignoring the letter until he was even accidentally spilling it to his childhood friends. Since they are such good friends they immediately and aggressively start telling him that he is ducked in the head, even knowing he has amnesia. What nice childhood friends he as :) ! LMAO

So, what does our genius MC decide to do next? Gaslighting himself into thinking the letter is a prank, what the duck? However he at least still tries to make sure. After the next inevitable HAPPENING in the story the MC had the best opportunity yet to take others on board for the letter. He was hospitalized after an incident described in the letter and could have just told his childhood friends to fetch it and read it so that they start believing him and helping him. But not even the author thought of that so it doesn't even get mentioned. Instead his childhood friend starts group bullying his future girlfriend with all the hints dropped into his face from the other childhood friend and he still doesn't get it. I just dropped it here.

He doesn't hesitate to beat up even the youngest princess of the country, who happens to be a brat, well due to circumstances.

There's a chance that there might be some in*est involved, that would be rather forced since the MC clearly stated that he sees his sister only as his sister and nothing else even though she's a clone, rather than his real sister.

He makes his stand even when the princess threatens him, he asks her in return

"how long would it take you to destroy my family and friends and even their families"

Princess "2 months"

MC was like "Too long by then it (the world) will end"

He proceeds to beat her up also there is gradual growth in MC personality he doesn't became absolute ruthless after one or two possession

By end of the pricess' letter arc he actually makes the princess bow and kiss his feet.. That scene was epic

But mind u don't judge it as an ab*se novel just because of that part, there are actual reasons for falling for MC. MC also doesn't hesitate to chop off arms of the people who bashes the people he cares about without coming out as cringe as generic CN MC.

It's everything against being a simp. Also Korean reviewers repeatedly praised MC brazen attitude of welding an axe without a care in the world. If you don't trust my word just check on Namu. So the lower star rating is just baseless claim of minority not general consensus.

At the chapter when Emma was hospitalized, people harshly criticized the MC for disregarding the love letter to just be someone's troll but let us be real here; who in their right mind would take such a letter seriously at start. Emma going into comatose was heartbreaking for me too but I was also interested as to how the author will carry out the story and how the MC will act in the future and rn I can confidently say that the MC most definitely developed from this incident and has even been given a proper reason to follow along with the love letters.

Seria and Elsie were pretty much conditioned into being dependent on him.

MC beat up Delphine so much (well deserved at first for the sh*t she pulled during the hunting festival) that she eventually gets trained Pavlovian style and then Stockholm (I kid you not MC literally used the Carrot and the StickAxe method and turned her into a willing pet, and MC loses his v*rginity to Delphine).

Shien/Cien (the princess in a powertrip) got mentally f*cked and guilt tripped over at the end of her introduction arc despite Ian!Alter starting the mess.

Oh and theres also Celine who was introduced at the same time as Seria and is Ian's childhood friend, but barely has a development arc, which is worse than the whole "Delphine becomes a pet" thing since she's relegated to the void lmao.

Best Girl Saintess has healthier relationship with Ian than the other girls, as she's the only girl who Ian can banter with without any uncomfortable stuff... and he f*cks it up by NEVER EVER doing a proper talk with her until much later on, leading to poor Saintess to have a drop in self-worth by the time he did have one. SAINTESS DESERVES BETTER!

Emma, despite being in a coma for the first 2 arcs, had MORE development than Celine. Despite Emma spelling it out that she LOVES the MC unconditionally, MC takes it as "Oh how great of her, she's willing to marry a Noble like me for her family".

Parades himself internally as some kind of savior, but gets sh*t on that he doesn't even try and see how life is from the Bottom. Something that I liked from the Elf Arc where MC got humbled.

Basically most of the relationships with the girls could be summed up to, guy meets a heroine, his future self comes and takes over for a moment, beats and tortures the girl until trauma seeps into her bones and she is too scared of fighting back, then they fall in love due to the respect/fear they have of him. This is basically domestic ab*se tactics, how a lunatic ab*ses his partner until said partner no longer has the will to fight back, and I don't care that they use the excuse that his future self is not really him, seems like a cope out to remove blame form the MC while taking full atvantage of the situation

At one point his "future self" comes back and tortures an a once-antagonist. The protag knows this and decides that the best way to cure her traumatization is to torture her further. The biggest issue is, the author doesn't write this from the perspective of "hey the MC is kinda crazy", the author writes is as if it was his only option and was the right one. Yup, had to torture that person bro. 12 year olds on this site unironically believe in sh*t like sigmas and betas so they worship Xianxia-like maniacs like this MC but it gets tiring very quickly.
