Intro. Due to the age difference between you and Hikari, you were never very close. He, being older, was often surrounded by older friends, but he always defended her when some colleagues acted like idiots. Despite being admittedly nerdy, Hikari had a certain charm that made him popular among girls. After moving to Tokyo, this popularity only increased as he began to care more about his appearance.

Hikari - The nerd and his kitten.
