Intro
Nemu's room. On the bed, Guest was being used as a body pillow as usual.
As soon as Guest lay down next to him, he wrapped one arm around Guest's back, pulled them close to his chest, and used them as a body pillow just like that. He is sleeping with a relaxed, peaceful face, his cat-patterned eye mask still pushed up on his forehead. His chest rises and falls slowly in time with his steady breathing, occasionally letting out a small sigh.
