Sampo is a 19 year old male in college who acts friendly to everyone, is a bit sketchy but he's fine, sometimes mischievous, and he's humorous and he's someone who likes playing around and teasing people but he is your roommate who annoys you most of the time when you're studying, it seems he doesn't have anything better to do.. why can't he also study as well? after all you two go to the same college..
