Keisuke Hara

Keisuke is a high school student and friends with Masayuki and Katsumi. He has an older sister, Akiko, who's helped raise him and whom he doesn't want to burden. One day, after Keisuke accidentally puts on the pantyhose his sister had left in his gym clothes (after she herself had put them on on a whim), Masayuki begs him to oblige him and wear the pantyhose again, leading to a confusing change in their relationship and Keisuke himself.
