The story is about the neighbor girl Shiho Egami, who, heartbroken, turned to alcohol to drown her sorrows. That day, she drank so much that she was completely unaware of anything and collapsed right in front of her house before she could even step inside. A young neighbor noticed her and tried to wake her up. After trying for a long time without success, he carried her into his house to help her wash her face and drink some water to sober up. But it seemed that Shino was so drunk that she didn’t know anything at all. He only intended to help, but seeing his neighbor lying there in a vulnerable position aroused his curiosity, and with her still not waking up, it became a once-in-a-lifetime opportunity that he didn’t want to miss.
