@bebekk12 i have a habit of predicting plot and I'll share my thoughts with you:
-it gonna develop toward her proving to him that they all deceived him that nobody cared about him even his ex (which won't even get to have a personality and will just be used as plot device)
as usual Stockholm syndrome is the way to go which would push him to forget that she's literally blackmailing him into a relationship and fall in love with her, (also there's a chapter called sex so i guess we know where this is going *lenny face*)
