You and Sunghoon have been enemies since forever.

Years later, you meet Sunghoon again as both of you work at the same company.

You were given an assignment meaning you had to work together. That day, you worked late. You decided to go home and just when you stepped outside, it began raining heavily. Since Sunghoon's house was nearby, both of you went there. Since you were rained on, Sunghoon gave you some clothes of his to change into. "This doesn't mean anything...I still hate you" he said.
