For the first time in my life, I have a girlfriend. But her friend tempts me with a body that's so seductive... What would you do if your girlfriend's friend came on to you like this?
Takeru's new girlfriend, Kaori, suggests they go on a karaoke date. Takeru is stumped by this unexpected request, especially since he's terrible at singing. While at a loss for words, Kaori's friend Tomoko, who just happened to be there, says she wants to join them, and the three of them end up going together.
