He hasn't had a girlfriend for years. Nishino has been living a lonely life. His only pleasure is talking to Reina (Reina Nanjo), the housewife next door whom he secretly has feelings for. But she is out of reach. He was happy just being able to talk to her. But now, Reina is right in front of him. "If you don't mind...can I stay over?" Apparently, she had run out of the house after a marital quarrel. The Reina he admires is staying in his room. It's a dreamlike situation, but can he really endure it as a man? Nishino hesitates, but he can't turn away the weakened Reina, so he welcomes her in. With mixed feelings, the night begins with just the two of them.
