Kim Woo Bin confesses his love to Sulli and becomes a strong love rival to Min Ho.
In the 10th episode of the SBS drama 'To the Beautiful You' that aired on the 13th of September, John Kim (played by Kim Woo Bin) makes a love confession to Jae Hee (played by Sulli).
When John Kim came from America and took care of Jae Hee, Kang Tae Joon (played by Min Ho) saw this and became jealous. Jae Hee thought that he was good to her because he was just a close oppa, but in reality he had feelings for her.
Later, John Kim dresses Jae Hee up in girl clothes and takes her to a party. When they were alone, he confessed his love for her.
John Kim stated, "Jae Hee. I stayed by your side and watched you since you were young. Same goes for right now and I want to in the future as well. I want to stay by your side from now on. I am so embarrassed I think I'm going to die but since I already started I should say the rest. I am confessing my love to you right now. Think about it and get back to me. I will be waiting."
Later, John Kim meets Tae Joon and says to him, "If you aren't going to make Jae Hee happy, if Jae Hee can't be happy around you, then let her go. I like Jae Hee. I won't make it hard on her like you do."
On the other hand, in this episode Seol Han Na (played by Kim Ji Won) finds out that Jae Hee is a girl.
