Kato and Yumino started their careers at the same firm, but their relationship has been defined by constant friction rather than professional camaraderie. While they entered the company together, they act like oil and water, with Yumino frequently criticizing Kato’s lax work ethic and his tendency to prioritize drinking over data accuracy. This intense rivalry masks a hidden tension that finally boils over after a company-sponsored night out. When Kato drinks far beyond his limit, the responsibility of escorting him home falls to Yumino, setting the stage for an unexpected turn of events that changes their dynamic forever.
Once inside the privacy of his home, the alcohol-fueled inhibition leads to a sudden shift in their interaction. Seeing Yumino in a vulnerable moment, Kato acts on a buried impulse, aggressively pursuing her in a way that reveals the unspoken chemistry between them. Unbeknownst to him, Yumino has harbored feelings for her rival for a long time, and she welcomes his advances, interpreting his drunken boldness as a genuine sign of affection. Their encounter is raw and intense, bridging the gap between their professional hostility and their secret desires, culminating in a night of uninhibited physical exploration that neither expected to share.
The following morning brings a heavy dose of confusion as the haze of alcohol clears. Kato wakes up to find himself naked and Yumino dressed only in her lingerie, forcing him to piece together the events of the previous night. While his memory of the encounter is fragmented, the reality of their situation is undeniable. This office romance drama perfectly captures the transition from workplace annoyance to intimate connection, offering viewers a compelling look at how quickly professional lines can blur when chemistry takes over.
