Asaichi, looking to be more popular with the ladies, starts a band with his friends. Leading his new, small-time band as the vocalist, he is joined later by a supporting bassist named Yoru. However, during a bit of post-concert “fun,” there was a small accident, bringing Yoru’s feelings for Asaichi to light. Normally, the thought of being with another man would disgust him, but after Asaichi heard Yoru sing, he was overcome with lust, and violently desired to feel Yoru day after day. This is a story that centers on Yoru and his one-sided love, his rapidly growing desires, and intense jealousy… Where will these feelings take us?
