though I somewhat agree with you on how it probably isn't biphobia...please remember that you do not speak for all bisexuals when it comes to what's biphobic or not. People get offended by different things, and it's not always all that obvious that some certain things can be biphobic, homophobic etc either. Some things are in between the lines.
Seriously, as a Bi person this is 100% not bi-phobic. I didn't even think of that whilst reading it. The uke never said or thought anything bi-phobic, it was insanely clear throughout the chapter that he has self esteem and self worth issues as he kept calling the seme "cool" and someone who wouldn't be with someone like the uke. Literally all his thoughts were positives and he never thought "omg will he cheat on me?!". All he thought is that he's cool, social, good looking and too good for him. If anyone manages to read all of that with no indication of biphobia and a clear proof of someone with personal issues then please learn about context. Context matter, understanding the characters natters, 0% biphobia found. ( ̄へ ̄)
