@donoghu legally, Nasa is an adult, yes. But this is the first time he's ever dated a girl, let alone marry one, and he just recently turned 18 since he and Tsukasa married shorty after his birthday. Mentally, he's not an adult.
I think people hate Henry too much. It's obvious that Henry was forced by his family to do all this, they set it all up and he just played his role, and he didn't have any ill intent towards Amelie.
I think Nasa has lived with Tsukasa for much, much, much, much longer than he realizes. I think he's a being that will die, and be reincarnated once more and Tsukasa is immortal. That's why Tsukasa agreed to marry Nasa right off the bat. She knows him already.
It's also why he might be good at...
@Kami_Nana it's just a really dumb trope that runs off the same formula every time, and the people who like it always say that vanilla is boring...When NTR H is so predictable. Literally the girl could deal with it with her lover as a couple. That's why they're together.
@Kami_Nana true. And they're always super submissive and never fight back against the guy. And then they always have those inner dialogues where they're like, "x-kun... you'll still love me. Right?"
