The main character has a fiancée - Irene.

So he ends up in a situation where he is between Irene and Elf B*tch (Siana or Siene? Whatever let's call her elf b*tch.) She knows well that he is engaged, but completely disrespects that and makes advances on him. Very obvious ones. Irene does the same but she is bit shy (She is his fiancée so it's alright.) The biggest problem I have with this is the Main Character. What is he doing in that situation? Nothing. That indecisive c*nt does absolutely nothing. In front of his own fiancée, he lets another b*tch get touchy with him. FFS.

also, Amy is the best girl (I hope she becomes part of the harem), closely followed by Irene

Something happens and people start suspecting MC, even MC agreed that he was suspicious and even he would find himself suspicious while going on a rant about how he is an adult and can forgive the other kids (they are like 16-17) of whats going on but then goes and have a mental break down next chapter like a Karen in fast food.

After that he make this misunderstanding something huge and basically create a mountain from a small molehill and start to act like a 2yo throwing a fit and the other kids react like this is the end of world. They start crying and throw themselves on his feet.

At this point you probably already get the idea from other reviewers about the plot, characters and the world building. Also the structure of the novel. So I'll just focus on one point people who probably only read the first 10 to 20 (or even 40 chapters) don't think too much about and that's also what this novel turns into, the relationships of Theo (MC) and how it is (badly) written.

First of all the portrayal of female characters is atrocious when it comes to behavior in society. Theo our protagonist was highly despised at the beginning of the story for some dirty evil stuff he did, but he was replaced by a transmigrator who happened to be a "living wiki" of said game after playing the game and getting most if not all its endings. Now here is a huge plot hole, it he beat the game (being one of the very few to do so in the whole world which makes no sense to me. It's like the author totally underestimates gamers in general) how come he didn't get to know the good feelings of the characters in the good endings? Sure he is always afraid to make a relationship with X characters because they supposedly end his life in their bad endings, but he never ever explains about their good ending. It's always negative and overly dramatic you can't take it seriously.

Now from all the characters the one that I want to talk about a bit, regarding this issue with relationships is his fiancée, Irene.

She's one (of the many characters) that end his life in the bad endings in the game. Of course that is when Theo (the character) acts like a total villain. Since he is not that Theo you might think he can do an effort to be in good terms with the girl that will eventually become his wife but no. The author decided to give Theo an annoying "treat" that activates when he isn't acting as a pride noble (he is the son of a viscount family).

Okay so that makes a bit of sense except the trait also acts one way or another depending on how overly complicated the author wants to make the story. For example, it will force Theo to act like an annoying sob with Irene when just wants to approach him because his pride, but in other instances he will allow other girls to flagrantly flirt with him in front of his fiancée, in public (if you think about this carefully that would ruin his image and reputation further) with tons of people watching and the poor girl (Irene) being humiliated by the act without him doing anything to stop the other girl (how come his noble pride won't act up in these cases? That would 100% tarnish his reputation and make him look like a cheater).

So back to Irene. The poor girl loved him since they met as children. She fell in love with his good looks at first. Even though some people might criticize that let's not be hypocrites, we all fall in love for that very reason at young age specially. Anyway she was repulsed as they grew up by his actions. However after his transmigration and change in attitude she falls (slowly) in love with him again.

Irene is indeed the best written character in the novel (Mari Jane, yeah no joke that's her name, the hero teacher is not as good as Irene but also well written). She actually has many POV chapters and you get to know how she develops and thinks throughout the story. However Theo turns into a typical japanese protagonist (I'm aware this is a korean novel) with Irene.

First of all he doesn't want to get close to her (despite feeling attracted to her, but God forbid readers would read a speck of romance from this train wreck of a story). So despite her efforts to be and act like the most understanding and supportive wife to be in the world he only sees her as a convenient "character" whenever he needs to improve his swordmanship.

The worst part is him, despite claiming he won't act like the Theo in game and improve his image/reputation, not doing a single thing when other girls approach him with the clear intention of taking him from Irene, even in front of her.

He could easily defend his (obviously suffering) fiancée and everything would be solved but no. In fact he even participates in flirting with other girls to Irene's dismay.

So in conclusion, this is a waste of time for romance enjoyers and harem lovers alike. The harem is badly written and feels more like a NTR story. As a romance? None. It's just bait. Irene is stray in a novel she shouldn't have to be. MC is one of the most boring ever. The only reason I give this 1.5/5 is Irene and Mari Jane. The rest of the cast is a jok

for example after their first date, that was pathetic af because 3 uninvited girls of his 'harem' stalked them the whole time and even tried to shame her, despite Irene being depressed because she had to remember a heartbreaking episode of the past with original Theo, Irene tells him lovers hug when they say goodbye (yeah not kiss or smooch, just a simple hug is all she needed to lift up her spirits a bit). Well this clown thought "I did as much as coming to the date but a hug would indicate we are in a romantic relationship" so he said "no. Behave we are in public" turned around and went his own way. I mean...

an orc!

-Okay, so the MC has fiancé (a knight like fiance), in the OG story they're relationship is bad in the og story despite her actually still has a crush on the MC it got overshadowed by the MC bad and tr*shy attitude, of course ever since the transmigration and the MC change personality she pretty much turned completely head over heel for the MC

-Another heroine is actually like a long distant family of the MC, at first she has bad intention planning to take over the family head by removing the MC (in the OG game it said she killed the MC) and it seems pretty easy for her since she is the popular kid and the MC is incompetent, but her dream quickly shattered after MC transmigration. Extra: There was one arc where she and the "top student" group wrongly accused the MC of something but the MC proved them wrong and basically humiliate them, which made her overburden with guilt and emotionally wreck to the point where she bit all her nails and lock herself. I find it a bit satisfying seeing her fall from this "everyone likes me and im popular" persona to this emotionally wreck person who is scared of the MC. But later she become like a loyal subordinate (by her own choice might I add)

-Third heroine is probably the one im guessing who will have the biggest emotional wreck once her arc is finish, she is basically the strongest heroine (currently) and the rival of the Original game protagonist, she is also the first person who we see openly despise the MC, but after transmigration she is the one probably the most confused and affected by the MC change of attitude (she also part of the top student group who wrongly accused the MC). Though unlike the other she suspect the MC to made a deal with demon hence the change of attitude, so currently she is trying very hard to find out if thats true (even forcing the MC to strip). However, I feel like all these are just denial and frustration. her attitude seem very desperate, so I have a feeling her final development will be the most emotionally shocking

Theres also the stalker elf, assassin maid, and the.. uh... pe*vert big breast girl which you see on the cover.

The character got replaced by a transmigrator, so he acts differently from before. He was suspected for an incident, not even directly blamed but basically just taken aside and asked if he did it. He then proceeds to throw a hissy fit about it and act like they did something unforgiveable by suspecting him, going as far as requiring a sincere apology with heads bowed from them and he contemplated never forgiving them if they weren’t sincere enough. The worst part is one of the people who suspected him literally got on her knees to apologize to him, acting like they did something wrong while the MC chides them for being children for suspecting him. Like jesus christ is everyone involved here utterly braindead. He was LITERALLY the most suspect person there and thinking he did it was entirely normal. Again I feel like I have to reiterate, they didn’t even accuse him publicly, they just took him to a room out of the way and asked if he did it. The most recent chapter also has several ladies think he’s been possessed by a demon, which is entirely reasonable because his growth is beyond genius level now while he used to be utter tr*sh, and it’s clearly just an excuse from the author for them to want him naked since demon possession leaves a mark somewhere on their body. All this while he’s just someone they used to hate/look down on for being an utter as*hole until like a month ago and now they’re all so in love with him they’re willing to try to help him even if society shuns them for saving someone who made a pact with a demon. The only reasonable explanation is they’re so incredibly shallow (to be fair they are 15 year old girls) they fell in love with him for his looks, since he’s supposed to be incredibly handsome.
