Asking a matcha cake to talk is as absurd as asking a woman to keep a secret... The five plastic sisters were eating matcha cake in a dessert shop after school. They suddenly made a joke and made a bet if the matcha cake could talk to prove that their words were true. The curtain of a love story about pure love on campus slowly opened, and it kept getting messy and confusing. In the end, it was discovered that matcha cake can still talk.
