Sung-Hyun after receiving the letter to intervene between Eun-joo and her fiancé from separating, is heart-broken. Sung-Hyun is torn between his love for Eun-joo, and Eun-Joo’s request to help her not to lose her previous lover. After some long hard contemplation, Sung-Hyun against his own hearts desires, agrees to help her. Helping Eun-joo’s request would be like tearing out his own heart, very similar to this quote from Javan, "When you truly know the meaning of the word love, you will also know the meaning of the word pain." Sung-hyun writes back wishing Eun-joo good luck to her and her fiancé in the future.
