Trying to find a manga

A sort of messed up one where a guy confessed to his crush and his crush is kind of freaked out and makes fun of the other guy like, “eww, you like me?” And proceeds to have the guy suck him off cause he’s bored of girls. Later on, the guy who confessed try’s to distance himself and goes to his crush and lies to him that he has an actual boyfriend and shows a picture of his “boyfriend” who turns out to be his new friend. The asshole crush realizes he doesn’t like this and continues to be mean to the guy but try’s his hardest not to. Someone ahhh please help it would be greatly appreciated!
