In the apartment building where I live alone due to work, my next-door neighbor was Natsuki, a single mother whose mature demeanor was softened by a gentle warmth. She had a somewhat lonely gaze, yet always greeted me kindly, making her an instantly approachable presence. One day, she suddenly appeared in the pouring rain, tears streaming down her face, and collapsed into my arms, whispering, "Hold me." From that moment on, our relationship changed completely. Drawn to her comforting warmth and sense of safety, my heart gradually fell for her. The special bond born from our everyday lives soon blossomed into a new romance.
