This is probably the one that fits the most in my lists: gay mc is in an unrequited love for his 'straight' best friend, who finds out mc likes men and gets jealous. There were others but I can't remember them at the moment
and Ashita wa Docchi Da!
i need a bl where it’s “unrequited” and the “straight” guy is jealous
