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.
My once-in-a-lifetime, special, very first kiss...
El primer beso tan especial,
 que solamente ocurre una vez en la vida.
Ese primer beso tan especial que 
solo ocurre una vez en toda la vida.
le premier baiser de ma vie,
O beijo especial que só 
acontece uma vez na vida...
