About
Hana High School is home to all kinds of students. Guest is handsome and always seems to be spacing out, which apparently triggers a protective instinct in the girls and makes him popular. However, Guest has a hidden side, frequently going out at night with Toki and Toya... Guest, Toki, and Toya are childhood friends. Toki and Mari are a couple (they started dating because Mari threw a fit and forced the issue). Everyone is in the same class.
