1. The synchronization thing. This sucks. Essentially, the MC is neither Deculein nor Kim Woo-jin, but a mixture of both. I loathed the synchronization in the previous work, too. This time, however, it came at a much earlier time (right from the beginning) instead of arriving late and has hopefully no chance of devouring Woo-jin.

2. Chae Nayuns. There's a handful of Chae Nayuns. By this, I mean there's more than 1 heroine that has a love/hate relationship with the MC, where they both love him but also wanted to kill him at least once. Included, but not limited to in this list are Epherene, Julie and Sylvia. Probably Ellie, too.

3. Mopping drama. Mopping drama is the unfortunate event when Wooculein, neither Woo-jin nor Deculein, is forced to mop up after the original villain Deculein because he's a genuine ass and everyone hates him. It would be fine if all of the drama ever comes from characters that Deculein had wronged in the past, but the current Wooculein inherited Deculein's emotional intelligence of a brick and he is equipped only with a 5% ability to empathize, which is definitely Woo-jin's. What really sucks is when the current Wooculein gets hindered by past Deculein's words and actions, especially since they are already established facts with no room for discussion. Like the mu*der of a certain character's parent, or the mu*der of another character's parent, or perhaps the other awful stuff Deculein has done over 30 frickin years.

4. Why's everyone a woman? In the previous work, at least there was Kim Suho to fall back on when lacking in male screentime (Jonghak to a lesser extent), but in the first 100 chapters of this, all of the major characters are female except for the MC. This gets balanced later on, but that must have been the author taking in reader feedback. One of the rare male characters was even a trap all along, what the heck? She's 2nd best girl though, so I forgive it to an extent.

1. The characters are fleshed out. I especially love

Heroines have normal friendships with each other and aren't mere sock puppets for the author, they interact with each other even without the MC's intervention, they have disagreements, gripes, their own circles of friends or none at all, dreams, objectives. In one of the later chapters, the MC tells another character about the person he still loves (his ex), which one of the heroines overhears. Her reaction to this was to flop in bed and murmur, "I wish it was me..." twice, in sadness. It was something so, so small and it's these small, insignificant things that turns these characters into people.

2. There's two people that got isekaid. Well, so far. The other one is his ex, Yoo Ara. As of now, we still don't know why they broke up. She's suffering the same disease as the MC, where she's assimilated with a character. Neither of them know the other got isekaid as well, for now. Both of them can't recognize the other despite knowing each other for years which is kinda weird, but maybe that's because neither are acting the way they usually do because of their assimilation with the game characters. I just like that there's more than one transported individual.

3. Sophien. Yes, she gets her own number. Her development, her motivations and her reactions to other heroines are so well-written. She's in love with Wooculein and knows what she wants, even harboring an almost ugly jealousy of Julie, whether she's aware of it or not. She's even doing everything in her power to make sure Julie hates Deculein in order to make a permanent rift in the two's relationship.

4. The misunderstandings. Oh god the misunderstandings. The way they weave together are just so good. They would be so much better without the bittersweet, tragic drama. The way two characters misunderstand MC and they think he's dying because of a precedent case and confirmation bias, how they develop by themselves believing he will die in the near future, how they might reveal it to other characters and how that might affect certain characters, all this anticipation is enough to drive a woman mad.
