EBWH-391 | I got to sleep with a blonde, promiscuous woman who showed up to our former mentor’s memorial service dressed completely inappropriately for the occasion. — Jin-ai Kiyomiya

In this story, Yuto returns to his hometown for a memorial service and reunites with Jin-ai—a girl he had a crush on back in his student days. He is shocked to find that Jin-ai, once modest and refined, has transformed into a flashy, blonde-haired "gal." Following the memorial, Yuto and his former classmates gather to reminisce, but, fueled by alcohol, the situation spirals into a wild orgy. Jin-ai, offering no resistance, engages in lewd sexual acts with three of their classmates. Yuto witnesses this, and later, he finds Jin-ai exhausted from the drinking and sex, and decides to look after her. "Hey... what did you think when you saw that?" she asks, provoking him. The orgy begins anew—and it turns out that Jin-ai had orchestrated the whole scene, dragging everyone into the chaos just so she could force the shy Yuto into having sex with her.
