i love that for her! she would just get tired if she were with him & have to be a nanny like 24/7. i don't really see them together
plus i hate the cliche that every single person we met in the manhwas has to be married or in a relationship at the end of the series, and especially when their partner is just someone they spend the most time with. they have a good working relationship and she's the best aide he could have, i hope the author doesn't ruin that by putting them into a relationship out of nowhere.
