Characters development

I'm in ch9 and I'm on the fence about keep reading, is this getting more believable? . I can believe tha people can fall for people regardless of their preference until that point but I have to say I didn't see a credible development for this couple. I mean, half of bl is straight man magically falling in love with guys, but it seems unrealistic in bl and also in this... you know what? I don't need a reply, I read my own comments and it hit me, I'm readin +18 content in an illegal site, not an OpEd. I should shut up
