Soo-Won treated Yona like his sibling,[18] and always looked out for her safety. Everytime she felt down, he will come up with ways to cheer her up. When Yona confessed to him, Soo-Won admitted that he does not reciprocate the same feelings towards her, but he is touched by her feelings. He also made clear that he is aware of her as a woman as he can no longer hold her hand or sleep together with her because he will be getting nervous if he do so.[19]
Even though he betrayed Yona, he still worries for her. When he finds out from Kang Tae-Jun about her “death”, he becomes blank for a moment, unable to process anything for awhile due to shock. Also, when they meet at Awa, he hides her from his men to prevent them from knowing that she is still alive. After seeing her safe and sound, he leaves Yona with sadness painted on his face. Because Yona was someone who gave him warmth back then, it is hard for him to forget her.[20]
