On the 14th episode of the SBS Wednesday Thursday drama 'To The Beautiful You,' that aired on September 27th, Cha Eun Gyul(Lee Hyun Woo) and Goo Jae Hee(Sulli) decided they would remain as friends. But Lee Hyun Woo still couldn't get over his feelings for her. 

Cha Eun Gyul decided he would stay next to Goo Jae Hee as her best friend. Cha Eun Gyul tried to hide his feelings. At a moment, he suddenly had to go to the bathroom, so he went into Goo Jae Hee's room and opened the bathroom door.

Goo Jae Hee was taking off her shirt, and her back could be seen. She was shocked that she was caught by Eun Gyul, while she was wearing a band around her chest. She hurriedly wore her shirt again. Cha Eun Gyul asked, "Squishy. Goo Jae Hee, you're a girl?"

In the preview for the 15th episode, Cha Eun Gyul stated, "were you playing around with me? If you genuinely thought about my confession, you couldn't do this," and this made viewers wonder what would happen to their future relationship.
