In "Heart to Heart" Ahn So Hee was very forward about her feelings for Lee Jae Yoon.
On the 10th episode of tvN Friday/Saturday drama "Heart to Heart" broadcast on Feb. 7th, Ko Se Ro (played by Ahn So Hee) started to show that she had secret feelings for Jang Doo Soo (played by Lee Jae Yoon) and expressed them to him.
On this day, Ko Se Ro went to the police station where Jang Doo Soo was working. Here, he started to take charge of all the housekeeping and cleaning. Ko Se Ro saw Jang Doo Soo walking out and suddenly blocked him. He started to pretend that he was acting cute and said, "My next role is one of a police officer. So I decided to come here to experience what it's like to be a police officer."
Ko Se Ro saluted him. He said, "Dedication. I will work hard and be diligent from the bottom up." Jang Doo Soo said, "Does your older brother know that you're like this, Se Ro?" Ko Se Ro said, "Well we don't meddle in each other's business. He's who he is and I'm just me. That's what we're like." With this, she showed a stronger personality.
