and i just can't wait til the day when you knock on my door (слэш)

Yuuri’s heart had just about given out when the apartment door in front of him opened to reveal his (definitely not a crush) favorite customer.
Whose name was Viktor.
Who, instead of the workout clothes or polo and skinny jeans he usually favored, was dressed in an overlarge sweater and pajama pants and brightly colored rainbow socks.
And who had a large, plastic medical boot on one foot.
