Looking for manga title

Okay so I’m trying to find a manga I’ve seen on here before that seems like of like a shounen manga but there’s a guy that also likes the main guy character. So a boy boy girl love triangle. The mc seemingly ends up with the girl....but then they break up after a couple of years and the final chapter shows us he actually ended up getting married to the guy he turned down in high school. I can’t for the life of me remember the name! Pls somebody must know what I’m talking about
