MrNopeNope's manga / #Unrequited love(3)

Yuuki has had an unrequited love for his friend Hiroya ever since high school time. Hiroya always has a girlfriend, and as a man, Yuuki knows himself out of Hiroya’s romantic target pool and so he just can’t confess. He planned to stay as a good friend forever. One day, he drank with Youichi, the only one who knows about his love, but the next morning he woke up to Hiroya kneeling before him! Apparently they did it under the drink’s influence, but Yuuki didn’t have any memory at all

Summary Hino's a popular, good-looking guy who's been harbouring a crush for the eccentric Yaku ever since they were in high school. Even if he's fawned over by girls everyday, the one who's most important to him won't give him a second glance! One day, quite unexpectedly, Yaku ends up agreeing to go to a drinking party with Hino's group when a girl asks him out. Irritated, Hino randomly propositions him, and they actually end up becoming sex friends

One of the best Mangas ever!
