The time of the graduation ceremony has come. Naoki decides to stay on at Tonan University, but Kin-chan, who didn't pass the entrance exams, thinks of his future and decides to find employment. Class F winds up at the same hall with Class A for their respective faculty thank-you parties; a clash between them ensues, and now the mood turns grim. Naoki eventually teases Kotoko in front of everyone. Kotoko gets back at him by exposing his boyhood transvestite photo to everyone. Furious, Naoki calls out Kotoko, and suddenly plants a kiss on her.
