Sulli's back hug to Lee Hyun Woo makes his heart flutter.
In the 5th episode of the SBS drama 'To the Beautiful You' that was aired on the 29th of August, Cha Eun Gyul (played by Lee Hyun Woo) was not able to hide a smile after receiving a back hug from Goo Jae Hee (played by Sulli).
Cha Eun Gyul, who still thinks Goo Jae Hee is a boy, becomes confused after his heart flutters every time he sees her smile. He considers sharing his problems with his roommate Min Hyun Jae (played by Kang Ha Neul) but decides against it and anguishes by himself.
He then thinks about how he wasn't able to give Goo Jae Hee CPR after she had drowned and how Kang Tae Joon (played by Min Ho) pushed him aside and did it himself.
Later in the hallway, Cha Eun Gyul says to Goo Jae Hee, "Cheer on Tae Joon for me," and turns around. Then Goo Jae Hee gives him a back hug and says to him, "Thank you. If it weren't for you it would have been very hard for me."
