A recommendation maybe
so i don't know what the name of the manga is anymore but there was a biker gang and the leader didn't let anyone ride his motorbike but then there was a younger student who somehow thought it was really cool and he was allowed to ride there and at some point they had something together was also a yaoi ٩(๑❛ᴗ❛๑)۶
