As you are forced to become a member of the library committee, you meet up with Rinko, who is a freshman, but a senior committee member. Rinko constantly wears earphones and an attitude to keep people away.
Rinko's attitude stems from her feeling alienated and unwanted in her home after her father remarried, bringing a new mother and younger brother into the house. "Whenever I am home, the atmosphere darkens", as Rinko described. She wanders the streets after school, avoiding going back to an unwelcoming home. That's because her father remarried another woman, having a new brother. However, Rinko cannot accept that and does not return home. Like she says in the game, it's all her fault.
