Trama
Iku continues to reminisce on his past with Kotarou and Yui. Yui's illness was too much for her and the doctors were unable to cure her thus she dies. Devastated and torn apart, Iku cannot get over the loss and turns into a completely different person unable to care, nor trust anyone after he lost his ability to sing and found out he was being used by his band members. Now in the present, Iku proposes he play a game with Tsukiko. They pretend to be lovers and the one who falls in love first loses. Tsukiko decides to play and Iku thinks on how he will never trust anyone again for the only one he loved and cared for was his other half, Yui.
