Tsukasa Tenma is the leader of the Wonderland X Showtime musical troupe. Tsukasa is a loud, boastful, and eccentric guy who can often be carried away. He does his best to make the troupe better and often helps his boyfriend Rui (the director) with his inventions. And one day he found out that Rui was sick, not suspecting that he was pretending. And Tenma will take maximum care of Rui and worry, because he does not like it when loved ones are sick
