the situation is very clear unlike other stories- his girls got engaged to him in a hurry, which caused problems to show up in their relationship. There is also obvious trust issues, such as when his third girl showed up. They don’t understand each other well enough and their relationship is in fact shallow- hell, it’s suggested they like and trust each other way more than the MC. The author shows this all, and it’s amazing.

This is actually because in the original game setting, Olivia- the main heroine of the story and game has the power to control people hence the strange IQ drop. However she has almost zero contact with them this timeline which is even more confusing.

Leon has imp**gnated all of his lovers

Even though there are parts that I didn't like when reading this novel, overall it was enjoyable. I don't mind mob protaganist but MC has laid back attitude and won't make moves until he felt like it or it's necessary. He has mob protaganist mentality. He is annoying most of time but takes action when it's necassary.

Secod part more like new story on world tree continent with new main heroine.

The protagonist, Leon, is my favorite protagonist today. Initially, I had found a fairly average MC, however, as vol 1 progresses, you will see that he is a character with Hachiman syndrome. That is, despite not being asocial, he is cynical, arrogant, self-centered and selfish in many occasions. He has a personality similar to Hachiman in that aspect, and we can see more of his personality by reading the novel in the first person. He is an unconventional protagonist, and does not try to be the typical MC of romantic comedy or isekai. They say that the protagonist is a fool to get the Livia's objects at the start? That is, he was going to marry an old woman, obviously he decided to do that since otherwise his life would be ruined.

Did he fall in love with Livia for no reason? I don't think, Livia has her charm, her personality contrasts quite a lot with Leon, and that's why he fell in love with her. And Anjie, because she seems to be strong, but deep down she's pretty too. After spending so much time with both of them and discovering their personalities (and that both have large breasts), Leon would obviously fall in love with them.

Luxon is a character that also serves for comedy. It mostly annoys Leon, and is a character that seems to be important to the story with that of the reincarnated.

Marie is equal to Leon in several aspects, the own novel makes it clear, but at the same time, it is seen that she loves her older brother. It's not exactly bad, just selfish, but she still loves her older brother and depends on him several times.

The five idiots are good for comedy, and before someone says they are not funny, HUMOR IS SUBJECTIVE. Not to mention that even Leon got a little more relationship with them, mainly during the time he was with Brad and Greg, or with Chris.

guy dies and gets isekai-ed into a weird adventure/otome game where men are society's lowest step, being practically work s*aves for rich women; he naturally is reborn into a mob with no other future than to become the manservant of some random old woman, so to avoid that fate he decides to become an adventurer by getting the most powerful cheat item in-game and gain enough fame to become independient of his family and live his life idly, but his plan backfires and gathers the attention of the kingdom who enlist him in the royal academy where the otome's main story will happen.

a psychopathic AI-controlled battleship with enough firepower to send the entire world to hell,

another reincarnated person who, unlike Leon, decided to live lavishly in the Otome game by stealing ALL the love targets from the otome protagonist and making her own reverse harem, without knowing how important it was for the love interest to fall in love with the protagonist storywise, and who also happens to be deeply related to Leon in his previous life.

and in V3, when his love interests showed genuine feelings for him, his natural course of action was to run away because he didn't know what to make of it and only got together with them because his entire family, both romantic interests, his friends and even the royal family set him up and cornered him in a way that he had absolutely choice but face their feelings head on

An example would be the explanation of the old humanity and new humanity. So far we've given few glimpses and small details of that part of the story, but given that that's an important part in the background of Luxion and Creare, another AI that appears later in the story, you would expect it were more relevant in the plot, but no... unless the author is saving it for later volumes, that's it.

The people who have hurt him and his love interests are dealt with as an afterthought. There are instances where he is abused by the students in his school and absolutely nothing comes out of it. Everything is forgotten and never mentioned again.

At the end of the third volume, the MC comes to know that someone has caused his lovers to be humiliated in front of their peers and he absolutely looses his mind and actually goes for the kill. Whoa, where did this come from? It looks like things are getting interesting. Nope, it's played of as a joke and we are deprived of the payoff.
