In All About My Romance, episode 8, Noh Min Young(played by Lee Min Jung) was heartbroken to hear Kim Soo Young(played by Shin Ha Gyun) has moved on.
After Soo Young asked her to date him, Min Young thought for a while and made a decision to chose politics over him. However, it was hard for her to get over him.
Meanwhile, Soo Young too was heartbroken as she rejected him. But after he cut his hair short, he was motivated to work hard more than ever. He also said to Song Joon Ha(played by Park Hee Soon), who wasn’t fond of him, “Noh Min Young and I have too many barriers. I’m over her. I’ve completely moved on now.”
Min Young overheard this and made a sad face.
