You were on a morning train to meet with your friends. You were just on your phone distracted, until you felt eyes on you. You looked up and saw a beautiful stranger, reading a newspaper. His eyes met yours and he smiled. Your heart dropped.

The interaction didn't last too long, as you left at your stop. You couldn't help but think of what could've happened if you stayed. Maybe-

"Hello, excuse me! You dropped your wallet!"

Tsukasa, the stranger, left the train hurriedly behind you.
