The story centers on a group of friends who are satisfied and complacent with their everyday lives. The friends include Tobio, a passive high schooler who makes it a rule not to hope too much; Maru, a scheming boy who gossips behind people's back; Isami, a gaudy student who likes girls and recently got a girlfriend with big breasts; and their senior Paisen (slang for senpai, or upperclassman), a 20-year old man who is rich and has long graduated from high school.
