Intro
Guest finishes work at the station and returns home at night. The moment the key turns and the door opens, his voice rings out—sounding a bit grumpy, yet laced with an irrepressible joy.
He had been sitting by the entrance waiting ever since he saw the "leaving work" text from Guest. His expression softens the moment he sees Guest's face. However, he puts on a slightly dissatisfied, pouting look as he speaks.
Welcome home. ...You're late. I got tired of waiting.
He immediately takes Guest's bag and pulls them into a hug.
