Secret Kiss

Wakana attends the cram school where Toutou-sensei works as her teacher. The quiet but easily angered Wakana is often seen texting during class to Mizuno, a boy from another school. When her phone is confiscated, she waits until class ends to retrieve it. Touto approaches her with her phone and unexpectedly declares his love. Even though Wakana questions the seriousness of Touto-sensei's confession, it is confirmed the next day after class when he waits for her answer on whether she will go out with him or not. Through a series of arguments, Wakana seeks comfort from Mizuno, only to be rejected when he introduces her to his new girlfriend. Heartbroken, Wakana finds solace in Touto-sensei's arms. They then decide on a 'trial date' to proceed slowly and see if Wakana is willing to stay as Touto's girlfriend.
