Be My Boyfriend Episode 12

The whole school turns on Ji Na, and Seung Min can't be reached. The last person to speak to him was Han Na, and she told him that Ji Na was so mad about the contract being exposed that she never wanted to speak to him again. Ji Na realizes that Han Na is the one posting the hateful messages and confronts her. Han Na admits to it all, adding that she's never liked Ji Na since the day they met. Her only goal now is to make sure Ji Na has nothing and that no one likes her anymore. All of a sudden, over the school loudspeaker, Seung Min addresses the school regarding his contract.
