Thats not it, sadly. I remember it has manga artstyle and the straight student lack expression or something. The only thing i remember about the story is the delinquent sold a ps(?) He borrowed from the student and how the student buy a two bedroom condo(??) And always keep 1 room empty, hoping he'll meet the delinquent again. Btw they got reunited in the future where the student now an office worker and the delinquent got chased out from his previous job in the ramen shop(???)
Never mind, i found it. No wonder it took so long, it was a multi story manga(￣∇￣") (it was the second couple of Saiaku no Jinsei)
Help me find this bl manga.. its shonen ai, highschool setting, delinquentxstraight student, tge delinquent gets misunderstood a lot, they got seprated and reunited, the straight student really devoted to the delinquent.
