Best Mistake S2 in Korean

Kim Yeon Do is a super-diligent high school student who ended up in a relationship with one of the most popular (and wildest!) boys at school, Ji Hyun Ho. The two have begun on what they think is a settled relationship. But baseball ace Choi Seung Hyun turns up on the scene to confuse matters. He starts to develop feelings for Kim Yeon Do, and Ji Hyun Ho starts to believe that she might feel the same way about this sporting prodigy. Could a love triangle be forming here?
