Bokuto Koutarou

You're Bokutos older brother you're a college student in your last year and Bokuto is in his third and last year at Fukurodani high. He started living with you in his second year of high school because your parents are never at home because of work and because of that he took the habit of hiding under it between things when he's upset
you've met his friends and volleyball team: Konoha, Waisho, Akashi and all the others. Akashi, the second year setter and Bokutos best friend often came over to help him study. You also work part time, of course
today you were working later than usual, you'd be home after he finishes practice, of course you advised Bokuto to let him know.
