Donghae's girlfriend Jessica met a car crash three months ago. While Yoona, needed a heart donor right away or she will be gone forever. The hospital told Donghae, that Jessica signed in a foundation where she will donate her heart if she passed away. 

Luckily Jessica's heart passed all the needed examination to be an organ donor. Yoona, who was first on the list, received Jessica's heart. After one year of emotional, psychological, and physical tests. Yoona came back to her normal self.

While Donghae is searching who the girl is.

Can Donghae love Yoona's true personality or he will love her because of Jessica's heart???
