Yurika is shy, taciturn, and quiet, but she was attached to me. Her parents don't realize it, but Yurika is actually very curious about her sexuality, and I've been playing sexual pranks on her sister for a long time. One day, her parents returned to her parents' home because of her grandfather's injury, but her sister didn't want to follow her, so she gave up and called me, who was living alone, to stay at home.
