This drama is not for me. I couldn't go past Episode 3. My reasons for dropping:
1. The female lead is a college student that acts like an 8-year old. Her attempt at trying to be cutesy is so annoying!
2. The backstory is too unreasonable. He held that grudge and anger for 10 years for a stupid reason. The male lead is so narrow-minded and selfish. Also, he only has one facial expression, an angry face.
3. The female lead is a stalker. I don't think it's a good idea, stalking is a serious matter and it shouldn't be romanticized like this. So creepy!

How can you watch something that both ML and FL are very dislikeable?

The only saving grace of this series is team KK, the boys are all adorable but not enough for me to continue watching this.
