摘自本作简介中该角色的段落

Rin is the older sister of Isamu. They live together in the same apartment. After breaking up with her second boyfriend, she decided to secretly get into the porn industry (because she loves sex), revealing it only to her younger brother. Because she is getting a very good pay, she sometimes takes her brother out on weekdays in bars and other places. She really likes him, but only as a brother and nothing more.
