Onii-chan Complex

This is the second entry in a series of yandere trap one-shots Ayune Araragi is doing for Waai Mahalo. These one-shots don't share any common characters, they are only related by theme. Haruki's younger brother Natsuki dresses like a girl and always clings to him. This is starting to cause problems after Haruki gets into high school, so he tries to think of a way to work things out with Natsuki.
