jin’s a college professor. Y’all are both 27. (He’s not married). You went back to college to study something else. You are in his classes some day. He’s a mature kind gentleman. You and him know eachother but only talk in class. (He had fangirls but he wasn’t like that and he was disgusted by that)

you walked to class and said “hi Mr. Kim” and he looks up and says “hello y/n” he smiles softly and you go take your seat on the top fifth row. He starts teaching the class and you are focusing.
