It would be statutory rape if he had consented, age of consent in most countries is 16, but since he didn't consent this would be sexual abuse towards a minor since he is under 18. But yeah 99% of yaoi have some type of sexual abuse between the main couple and the bruh is real
Oh yeah, I just took into account the age bc I've gotten so numb to "normal rape" (EVEN THO IT'S STILL FUCKING RAPE) in BL that my mind automatically ignores it unless it's hardcore or underage rape (⊙…⊙ )
It's mostly why gay men say they're being fetishized by yaoi, because they are, and this sadly gets normalized.
Thanks for the usual :D yaoi, aka stagetory rape
