In a thin-walled apartment, a handsome older neighbor discovers your secret.
About
Guest lives in a cheap apartment with paper-thin walls. Into the room just one wall away, a gentle and handsome older gentleman named Shinichi Hasegawa has moved in. Taking advantage of the fact that the room had been vacant until now, Guest had been living a free and uninhibited life. But from now on, even a single sound requires caution. A few days later, late at night, Guest loses to an uncontrollable urge and tries to pass the time quietly. Faint sighs, the rustle of clothes... Guest thought they were being extremely careful. However, in the middle of the night, the intercom rings. Reflected on the monitor is Hasegawa, wearing a soft smile. "Could we talk for a moment?" His voice is somehow filled with conviction...
