Hae soo died. She left Wang so all alone in the midst of his reign that had just began. He never even got to meet her for the last time. The letters that were sent to him, what's the point of reading them now when there's no one to send his replies to? Changed him in the best way possible but ended up making the same mistakes. She stayed with him in his bad times. He regretted sending her out of the palace for the rest of his life, she never really left him though, that's what he chose to believe through those letters which he read everyday over and over again. Whether its her asking for apology when they first met, taking her away to see the ocean, or staring at the stars in the sky of Goryeo, he cherished all those memories till the end of his life, till he died at the age of fifty due to chronic illness. Hae soo meanwhile after a long time woke up in the present where she is taken aback by the flood of memories from goryeo as she stares at the paintings of the princes carrying the10th prince. The ritiuals and a giant portrait of Gwangjong of goryeo, 4th prince Wang so... How weird is it that a girl could alone change the lives of so many, touch their hearts in so many ways. Apparently none of the princes remained the same after meeting her. Nor did she. In her time in Goryeo she faced every bit of tragedy someone can. Deaths of the friends, family and most of all not being able to be beside 4th prince anymore. I hope you would love this journey where hae soo looks for the answers that always bothered her since she was in goryeo like why she was sent there, the purpose. What was the fate of Gwangjong later on? Why her, why him? And if there is Ji mong in this time then perhaps the 4th prince too...it won't be absurd. Because if there's just one teeny tiny possibility that he is... around her, she would find him by all means. Of course it won't be easy... But he promised. Do like the chapters!
