Manga title please! And thank you!

About a college guy who consults his friends about his lack of interest in girls, and his friends conclude he might be batting for the other team then. They recommend him to approach a classmate of theirs who's widely rumored to be gay, so he did.

Seme requests for the uke to teach him how it goes between two guys, so they become sex friends. Seme falls in love. Uke seems to treat him like just a casual fuck. Still, they end up confessing to each other.

Seme's friends are really open-minded and supportive.

I remember the seme having blond hair, and the uke having black(?)
