Oh now that someone else mentioned it, the artstyle is similar, looks like same artists with Love Factory. The first several chapters was just bruh. I like tsunderes because I can relate to them. Often, they know they were wrong for their violence but they just automatically do it, like on impulse. Now, for this manhwa's 'heroine', breh as if, but hopefully she is endgame. We have a sht mc over here torn and can't decide who he loves for 100+ chapters. So for the heroine, she's very tsundere, but she often is too much and doesn't apologize for her behavior before. Sometimes she did, but barely she does. There were barely thought bubbles where she thought the impacts she did was wrong. It was very bruh. I hoped she'd become better in her tendencies.
For the mc... You pos, she already told you she liked you multiple times and you still can't figure out when she says things that obviously mean or imply she wants you do it for her, so stop thinking "geez, what's wrong with her? What does she want with me?" Oh and you still can't decide who you really love between the two? Curse you.
For the other woman, oh I don't care about her. I don't care about the ''budding'' relationship between a former teacher and student, especially after graduation she kept touch over the years unable to move on from the feelings she gained towards him when he was in school. It's distasteful. But she used to be bullied, is emotionally vulnerable, of course she's going to fall with just simple encouraging lines from anyone. You have had a job for years, get therapy.
Art is good in the beginning, it worsened a bit as chapters went by.
All ain't really spoilers, they happen in like the first 10-20. It's a p-rnhwa so 50-80% its just intercourse, then the rest is plot development. So if you remove the intercourse part, then the main info I mentioned is like just maybe more or less 7 chapters.
Room temp iqs? Yeah, check the box.
