Looking for a manhwa

I need help finding a manhwa. I remember the side story was the main couple and it was set in old Korean times. In the side story the ml gets caught by the other leaving late at night and they go to the market together and ml said he’s buying gifts for everyone back home not just the other ml but when they get home the ml gifts the other ml this yellow scarf . one had blonde and the other had dark hair ? That’s all I can think of !
