Plot
We aim for the bowling high score... Next week, we watch the TV... Our senior friend is rich... Yes, our life is full of hope!

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 senpai, a 20-year old man who is rich and has long graduated from high school.
