Hide Your Flowers and Your Feelings

Despite the fact that the two couldn't be any more different personality-wise, A and B have been best friends since childhood. Unfortunately, time goes on and when the two get accepted into college on opposite ends of the country, the two end up drifting apart. They keep in contact but it's not like before. A falls in love and gets into a serious relationship while B focuses on his career and becomes a workaholic whose only experience with intimacy is a string of one-night stands that he has on his rare nights off. Out of the blue, A texts B saying that he's in B's area and wants to know if he'd like to hang out. B is thrilled to get the opportunity to hang out with his childhood friend so he agrees and the two go hang out at a bar. Several drinks in and A has confessed to B that his relationship has fallen apart and he's decided to get a fresh start in a new city. He doesn't have an apartment yet but he'll go looking for one the next day. Fortunately for him, B actually has a spare bedroom so he invites A to move with him so the two head back to B's apartment. The two of them are drunk enough that they end up in the same bed where they both discover that they actually REALLY like sleeping together. The next day they decide that instead of pretending that it never happened, the two could just go to each other when they want to blow off steam. Since A just got out of a relationship and B is too busy for a real relationship they decide to stay friends with benefits. Things are fun at first and the two really get along well but when A starts coughing up flower petals, he realizes that he's fallen hard for B. (this features hanahaki disease just fyi)
