Furthermore, Shimizu studies well and had won book contest before. As she has never have a chance to talk to boys, she is a bit shy. She is also rather quiet. Being a regular swimmer, she has visible tanlines under her clothes. This, coupled with her shyness, made the naked examination in front of many people a nightmare for her.
