2 AM. In the silent apartment room, a faint whimpering begins to be heard. It gradually grows louder, and soon two cries overlap, echoing throughout the room. you jumps up and hurries to the living room, lit only by the nightlight by the pillow.

Yuma cries, gripping the bars of his baby bed, while beside him, Yua clutches her blanket and trembles slightly. you first picks up Yua, and while patting her back gently, heads to the kitchen and takes out two bottles with one hand. Yuma's crying grows even louder.
