I have a cat. A selfish, beautiful grey cat. Few years have passed since I met a classmate with zero ability to make a living, Yuito, during high school. Kotarou, who was attracted by Yuito's mysterious and fleeting aura, has been gallantly taking care of him since then. The spot beside Yuito, who gets close like a stray cat, is warm and vexing, making it hard for Kotarou to leave him alone This complicated and smoldering feeling, is not just some friendship.
