When Gakupo fell in love with Kaito-san at first sight, he never saw him do anything serious except turning into a fool every day. "Master, since Kaito-sama's problem has been solved, can I propose to him now?" "Ah. I wish you success." When a human being as a Master falls in love with a mechanical singer, who can understand the pain? "I love Kaito, you can't change this fact." "Well, but there is one thing I know better." Basically, everyone loves Kaito, so let's get along well together!
