Looking for manga

It is about one of three friends from high school, he was in love with his friend but never told him. He met this man in bar and they hooked up. I know that at the end of the story they moved in together and the friend that he used to love got engaged. They are all happy and stuff. And there is a another manga about the third friend, he is together with his teacher from school. Does anyone know the name? (=・ω・=)
