Senpai no Mizugi

Honda is a dedicated member of his high school swim team, guided by the personalized coaching of his senior, Momotani. Although Momotani has already retired from competitive swimming, he remains deeply invested in Honda’s progress. Their strictly professional dynamic takes an unexpected turn one night when the two share a few drinks. In the haze of the evening, Honda discovers Momotani dressed in a woman’s swimsuit, deliberately attempting to seduce him. This startling revelation forces Honda to confront his own hidden attraction to his mentor, leaving him to wonder whether their bond can survive this sudden shift in intimacy. This volume also features Mizugi Kareshi, a separate story originally published as a doujinshi that follows a different couple navigating similar complexities. Atsushi and Yu were once inseparable friends, but Atsushi abruptly severed all contact with the quiet, feminine-looking Yu without explanation. The sudden estrangement appears to be linked to Yu wearing a woman’s swimsuit. When Yu eventually uncovers the truth behind Atsushi’s withdrawal, he must face the reality of his friend's far-from-innocent desires, setting the stage for a tense emotional reckoning between them.
