In All About My Romance, episode 10, Kim Soo Young(played by Shin Ha Gyun) and Noh Min Young(played by Lee Min Jung) almost broke up because of Song Joon Ha(played by Park Hee Soon).
Min Young kept talking about Joon Ha on their date. Soo Young was mad and said, “Stop caring too much.”
The two walked to Soo Young’s house. As Min Young asked why he took her there, Soo Young replied, “You’ve been talking straight about Song Joon Ha all the way to my house. Stop caring about him.”
Then they started to have an argument over Joon Ha. Soo Young got tired and suggested to stop the argument, but Min Young raged, “You made me upset, and now you’re trying to escape from this situation.”
