Morinaga Tetsuhiro has had a crush on Tatsumi Souichi for many years, which is a problem because Souichi is incredibly homophobic. In the prequel, Challengers, Souichi was very upset that his younger brother Tomoe had fallen in love with another man, only to find out that not only is Morinaga gay, but that he has crush on him. It is only through accepting that his friend is an ok guy, who is gay, that he gives up and accepts his little brother.
