I think this is a manhwa, but I don’t really remember, though TBH… Anyways, I think it was about a CEO and his assistant. And one of the seems that I remember is how the CEO said to book a dinner, and the assistant did, but she thought it was for the CEO and herself. But it turns out when she came to the restaurant with a dress on, he just wanted her to walk his dog while he had dinner with some associate LOL. she had to walk the dog and heels and a fancy dress or something like that…
