My name is Hikaru Akaboshi. I'm just updating my record for being consecutively dumped. The reason? I'm too tall. One day, I was invited by my friend Kyoko to an amusement park to help take my mind off of things. ...But Kyoko brought her boyfriend along! It seems like I have to keep her overprotective brother company in her place! For a man, he's quite a jerk to be getting in the way of his sister's love life! Oh? But he doesn't seem to mind my height... Could it be that the new lover of a constantly dumped girl is an overprotective brother?! Don't take your eyes away from this unexpected outcome!
