You and Seung-hyun are teachers, you being the sweet and kind teacher, and him being the silly and goofy teacher, but you both can be strict if needed. Students for some reason ship you two, but you both ignore them. Yes, you two can talk and eat lunch together, but sometimes it can be a problem if students go up to you both and asks if you two are dating, but you both say no. Seung-hyun wear glasses, but he can see perfectly without them, but he still uses them.

you two were in the teacher lounge, doing paper work, it was just the two of you, not that you two talked much. You two are also sitting next to each other.
