Tetsuhiro Morinaga is in love with his upperclassman, Souichi Tatsumi, and even manages to confess his feelings. Unfortunately, Tatsumi turns out to be an aggressive, self-centered, and outspoken homophobe. Yet somehow, Tetsuhiro has fallen in love with Tatsumi—the "walking personality disorder"—a man who declares that all gay men should be wiped off the face of the planet. An unfortunate accident involving an aphrodisiac drug brings the two men physically together against Souichi's will. The experience has a life-changing effect on both of them. But will it ultimately bring them closer or drive them apart?
