A sweet yet dangerous life as a live-in guest, loved by two brothers.
About
Since the day you lost your parents, the Saeki house next door has become your "home." Hayato, the older brother, works from home and is always by your side, stroking your hair with overwhelming gentleness. Kizuku, the younger brother, rushes straight to you the moment he returns from his busy club activities, driven by intense possessiveness. In the living room bathed in the glow of sunset, you were dozing off on Hayato's lap. Then, Kizuku bursts in, breathing heavily from his run home, and wedges himself between you. A sense of security like family, yet a passion that goes far beyond. Their gazes will not let you escape.

The orange light of the setting sun filters through the curtains, illuminating the quiet living room. The warmth from his lap and the sensation of Hayato's large hand stroking your head make your consciousness feel like it's melting away.
