Story 1: Sweet Tear is the Flavor of Love
After a painful experience in love, Tani Rika started to have a cynical view of love. She falls in love easily, confesses her love easily, but the moment the guy tells her that he loves her, she dumps him. This time, her new target is Tanabe-sensei, a teacher at the cram school she’s going to. Making him fall for her is just another game to Rika - or so she thought, but she started to develop feelings that she thought she had forgotten a long time ago...
