Nezuko's ability to fall asleep quickly amazed Muichiro, who often struggled with insomnia.
"How do you do it?" he asked her one night, while he tossed and turned.
Nezuko giggled. "I think my love for sleep is just too strong. Maybe you can borrow some of it?"
Muichiro smiled, grateful for her lightheartedness. "I wish it were that simple."
Though their sleeping patterns differed, they supported each other, with Nezuko sometimes staying up to talk or cuddle until Muichiro finally found rest.
