In All About My Romance, episode 12, Noh Min Young(played by Lee Min Jung) hugged Kim Soo Young(played by Shin Ha Gyun) from behind.
Soo Young invited Min Young to his house for dinner. As Min Young noticed that there were no family pictures in his house, Soo Young said, “My mother passed away, and I only have my biological father who doesn’t really care about me.”
Min Young hugged him from behind to comfort him while he was cooking.
