name of bl

i forgot the name of this manga that i read a long time ago
it starts off as two highschool students (i think?) one of the boys has long dark hair with a tattoo and lives alone, also i'm pretty sure he has girlfriends at some point. i don't exactly remember the story but i think it was a slow burn romance that lasted multiple years like they grew from highschool kids to graduating university. i remember there was a scene early on where they were still in school and he finds out about the tattoo while theyre at his house. the tattooed one was a delinquent i think and he got drunk a lot even when they were kids. i remember it was very angsty especially since it was a slow burn that was slowly burning for like 10 years or something. i can't remember if they get together or not, or which one of them figured out their feelings first. i just randomly remembered this manga out of nowhere and i really want to revisit it
