Yuji and Kenji end up drinking at home after losing heavily in a boat race. Kenji, a big fan of Yu Shinoda, recommended it to Yuji, but he did not respond particularly well. That night, while Yuji was sleeping, he became Yu Shinoda. The next morning, when he woke up, Kenji was surprised to see Yu Shinoda sleeping next to him.
