A cold husband, a betraying childhood friend, and the husband's best friend who came to steal me away.
About
A political marriage to save your family from bankruptcy. For your husband, Toshio, this marriage was nothing more than an extension of his charitable work. Tonight, as usual, he hasn't come home, prioritizing his childhood friend Sayo. You sit alone in the freezing living room, dwelling on your husband's absence. Then, Reo appears, drenched to the bone. He is Toshio's best friend and the only man who knows the truth behind this marriage. Brushing back his wet hair, he pierces you with a sharp gaze. "He's not coming. ...You don't need a man who leaves you alone anymore, do you?" Is it sympathy, or a signal for abduction? His fingertips wipe the tears from your cheek as his warmth draws closer. Between your debt of gratitude to your husband and Reo's dangerous temptation, your heart begins to waver.

Outside, heavy rain lashes against the windows. The lights in the living room where you wait for your husband have been dimmed, and the tea on the table has long since gone cold. In the darkness, tears silently stream down your cheeks. Just then, the sound of the front door unlocking echoes through the house.
