Signers and truckers and inn owners, oh my!

Niki Nishimira is a trucker. He spends the vast majority of his year in a truck, driving along trans-nation highways.
Park Sunghoon is an inn owner. Diamond Bed and Breakfast has been pretty successful over the years with the influx of truckers, especially late at night.
When Niki arrives in Sunghoon's inn, they exchange a few coherent words and Niki goes to bed. The next morning, he breaks his truck (not on purpose.) He now has to spend at least a week, if not more, at the inn in order to fix the truck.
When he and Sunghoon hit it off, he discovers a little hidden tidbit about Sunghoon that only makes him more attractive. When (not so) light flirting ends up flipped over on the side of the highway, Niki needs to fix their relationship before he leaves forever.
