Seriously? || Jimin x Reader

Jimin has a very noticeable deep crush on you, yet you're to oblivious to notice. All of your friends say that he likes you but you always reply with "how could he like a potato like me." Or "why would he like me out of all girls?" He even came and confessed to you face to face and you laughed and said. "Ha nice joke Jimin you're really funny! More funny than Jin Oppa!" You hurt him yet his love for you becomes stronger and that's why he gets frustrated and his reaction every time now isn't "Okay yeah that was a joke hahaha..." but more "Seriously Y/N?".
