@Rohen she probably just married him because he had money and because she wanted to have a "family". From earlier chapters it seems that he can't even satisfy her (pills probably were for him). There might be no love involved in their relationship and because we didn't see him at all he gonna be just forgotten. Im curious about the ending of this though, can it end as harem? If not i don't think its possible to end it good with MC chosing one of them.
Also there is still the date with Nayeon sister, wonder when it gonna happen xD
@Hejti the premise was that he was wary of his step mother because of that, so when he finds out that she really loves his father, he starts to open up to her, but then again pornwha logic...
@tokiioKH fr. Nayeon actually really likes him and she's just getting shafted. She's also the girl he originally really liked in the porn so it seemed like a no brainer
