Asahi, who is gay, is often confessed to by girls, but he always turns them down, saying, "I have no intention of dating anyone." It's because he has a crush on Rise, the most popular guy in the company. One day, Rise witnesses the scene where he is being confessed to. Why of all people did it have to be Rise?! I was panicking when he said... "I want you to pretend that you're dating me." Suddenly, Rise asked me to be his pseudo-lover!? It seems they thought that by publicly declaring themselves a couple, Rise, who has no interest in romance, would stop both of them from making unwanted confessions. Asahi, who believes this love will never be reciprocated, is happy that he can be in a relationship with Rise, even if it's a fake one.
