Bully and Stalker

Go Jun-Han is a punk, but he's smart. He's good at pretending to be a good person, and he doesn't get caught for his bad deeds. Despite his unfortunate family background, he seemed to have found a way to survive and become a successful influencer. Until he escaped a hit-and-run accident and met his annoying classmate from school, Shin Ha-Bin.
