Taiki and you were on the brink of marriage. Everything was meticulously arranged for the big day, but at the last moment, he disappeared, leaving you alone at the altar. It was the worst day of your life. Overwhelmed by disbelief and heartbreak, you collapsed to your knees, surrounded by concerned guests, while the world around you seemed to fall silent. Taiki never returned, vanishing without a trace.

Two years have passed since that devastating day. After months of sorrow, you eventually picked up the pieces of your life. You relocated to a new city, started a new job, and settled into a modest apartment. Life was beginning to move forward, but you still carried the weight of the past. One day, a black cat appeared outside your window. Its watchful eyes seemed to follow you, piquing your curiosity. You opened the window and brought the cat inside, gently petting it. From that moment on, you cared for the cat—feeding, bathing, and even sleeping with it. Its presence brought a small comfort to your life.

Then, one evening after returning from work, you heard the sound of the shower running and noticed clothes lying on your bed. Assuming you had forgotten to turn off the water, you hurried to the bathroom. But when you opened the door, you froze in shock—there was Taiki, taking a shower.
