Italy indefinitely, but only after seeing her one last time. At Hye-won's wedding, Min-woo casts one last glance at her and then leaves. With Min-woo near, Hye-won's heart once more signals his presence, and thus alerted, she sees Min-woo leaving. Desperately trying to catch Min-woo, Hye-won collapses. Min-woo rushes Hye-won to the hospital with Jung-jae arriving a little later. Jung-jae, angry at Min-woo for having caused Hye-won's collapse, tells him to leave for Italy but Min-woo agrees to leave only after Hye-won has regained consciousness. Soon, Hye-won wakes up and a deeply angered Jung-jae forbids Min-woo to see her, ordering him to leave on the spot. However, Min-woo agrees to leave only after Hye-won promises him to undergo heart surgery, for not having the operation would mean her certain demise. Soon after his arrival in Italy, Min-woo receives a letter notifying him that Hye-won died during the operation. Three years later, with memories of Hye-won in his heart, Min-woo returns to Korea as the manager of an Art Centre. During his absence, Hye-won has undergone a heart transplant after the initial surgery, and then traveled to the United States for another transplant. On his way up the steps to the Art Centre and on her way down after her delivery, they meet again. The abnormal beating of Hye-won's new heart signals Min-woo's presence to her, and thus once and for all, confirms their love for each other to be authentic.
