My Man's Man.

The campus couple Min U and Ji Na always have Park Wan around, and Ji Na starts noticing something strange. "Does Park Wan like Min U?" Her suspicions are all too correct, and even Min U can't hide his sentiment. Ji Na pushes Park Wan away, but despite her warning Park Wan kisses Min U in front of her, to which Min U doesn't refuse. In shock, Ji Na is left to ask what happened between the two.
