I feel like this is the closest one I've read http://www.mangago.zone/read-manga/baby_face_monster_moto_banchou_no_ore_daga_kuso_gaki_ni_ketsu_wo_nerawerete_iru/
This too has basically the same plot as the other two with a former delinquent and his admirer + the age gap

This one is a bit different but you still get the former delinquent/admirer dynamic and I liked it a lot more than the others
I want to read bl stories like this one any recommendations
