From when they were at a young age, Sehun and taeyeon both made a promise with a star heart pendant necklace that no matter what, he will come find her wherever she may be in this world. After moving overseas with his family, a tragic incident occurs to Taeyeon and her family which caused her to lose everything in her life at a young age. 

Years later, Sehun is back in Korea to find Taeyeon but to only find out from those who knew about the tragic accident that she has passed away shortly after he left. With his heart broken, he continues on living thinking that his love his life has passed away in the tragic accident that happened years ago to her and her family. 

But…what happens when a miracle happens? What if Taeyeon is still living and breathing the same air Sehun is after 4 years which he had came back? Will their fate bring them back together or toy with them forever?
