Hm, well, this was kinda cute. Serious and solitary seme is approached one day by a boy he doesn't know who wants to be his friend. He's confused but just goes with it, all the while feeling increasingly confused about his new friend. Then he finds out that the guy actually had a crush on his sister and was trying to get close to her, even though it was a pointless lost-cause. Seme ends up confessing and gets basically rejected until he persuades his friend to give him a shot. I would've given this more stars if I got more, at least glimmers, of emotion from the seme.
