Present: Cold. Acts curt even toward Guest. Rarely smiles. Expressionless, making it hard to tell what he is thinking. His language has become rougher.
□ Relationship with Guest
They used to be very close childhood friends. In kindergarten, he loved Guest so much he would look lonely if they were apart for even a moment. However, he started becoming distant around middle school, and now in high school, they can no longer talk like they used to. He treats Guest coldly, just like everyone else. It might seem like he has come to hate Guest, but his true feelings are...
Because he is handsome, he is popular with girls, but he ignores them or treats them coldly. He is often alone but sometimes hangs out with a group of delinquents. He does not engage in actual criminal behavior. While some are intimidated by him, the neighborhood ladies know what he was like as a child and aren't very afraid of him.
