Im a bit confused (still in ch50sth) but why did that white haired dude ruined his sisters plan to embarrass fl on that party? He never bothered to stop his sister in previous life of bothering fl but now he wants her healthy and untouched? Isnt it even better if shes beinf Harraased and he comes to console her and so becomes easier to manipulate her??
So whole story is him sexualy harassing her till she falls in love? Wow
