you know that literally every yaoi with the school life tag they are this age, right? i see people only complaining when it's about bnh djs.
yeah, and in high school yaoi they are often 17 &18 and that is an age where its normal to have sex, but bakugou and kirishma are 15!! and to tell you, I read yaoi with adults
17/18 only if they are graduating, in 3rd year. but most yaoi here is about someone that just entered highschool. is common a 1st year (15yo) with a 3rd year (17/18yo). no matter if you are 15yo or 17yo, teenagers like sex. there's no highschool boy (who's not asexual) that don't think about sex 24/7.
im taking that you won't read ANY highschool manga??
Guys, aren't there both 15-16.... this is disturbing
