The student council is busy preparing for a music festival in November. The music festival will take place after the students have finished their college entrance exam, so the student council will have to work on the festival as well. It would be amazing if they could invite btim to perform. He is one of the school's alumni, and he would be a perfect idol for miri. The two of them decide to treat each other to two cheesecakes, if they can invite them to the party. The handkerchief that was splashed on the ground is the same handkerchief that they used to wipe on each other's faces when they were in love. They decide to follow behind her and find her.
