Hyejeong and Seolhyun hated each other since they were kids. But Seolhyun actually had feelings for Hyejeong. Her feelings developed when they were in high school, but Hyejeong had given her stress and always getting on her nerves, very annoying, so she rather hid her true feeling and tried hard to hate this cheeky girl again.  However, her efforts failed miserably as the feelings were getting stronger.
