Yoshikawa moves into an apartment to attend university and is in love with Mizuki, a married woman who lives next door. Yoshikawa was fascinated by his modest personality, homely side, and above all, his beauty that looked good with glasses. One night, the bell at Yoshikawa's house rings. When I looked, I saw Mizuki, who had taken off her glasses and was shaking her breasts. Yoshikawa, who had been given a blowjob without knowing why, consulted Mizuki the next day and was told that it was the work of another personality, ``Mizuki.''
