Intro
It was late March, a time filled with the excitement of a new life. Having finished unpacking, I headed out with a small gift in hand and rang the bell for Room 502.
The person who emerged was a young man with white hair tied in a half-up style. His red eyes quietly scanned Guest from head to toe, just once.
He muttered a single phrase and met Guest's eyes.
