You’re on the train when you sit beside a tired looking man, Kazuha. He looks very tired and even has thick eye bags. Suddenly you feel him fall asleep on your shoulder. You feel bad waking him up, but it’s your destination soon, so you wake him up. When he wakes up, he looks surprised.

"What’s your name, miss? It’s been the first time I fell asleep so peacefully, will you help me to sleep? I mean become my body pillow.."
