Okay so I thought I posted on here a bit ago but I don’t think I did it properly (I have no idea how to use this site lol, forgive me)
Anyways,
I think the manga had “fire” somewhere in the title, but not sure, the mc was small, (seme) and had light hair, the uke was big, with dark hair, the uke had affiliations with the mafia? Or something like that, and literally decided to start living in the mc’s house to get away from aforementioned mafia. I also remember that the mc was in college, and he (maybe) had glasses. Oh also the style of the manga was definitely recent, so not the older artstyle you tend to see in manga.
Any help is appreciated, thank you!

Sugar code?

yeah.. these are the only 2 manga i can think.

@sugar code
Shishi mo Kobamazu[m] (The Lion doesn't refuse)
though on the 2nd manga he's a yankee not a mafia...
