During the episode of SBS ‘Rooftop Prince’ that aired on the 23rd of May, Park Yoochun shed tears for his longing for Han Ji Min. Lee Gak (Park Yoochun) becomes time warped back to the Chosun Dynasty and solves the mystery of the murder.
During the episode, Bu Yong (Han Ji Min) dies after intentionally eating the dried persimmons that had poisonous powder on them provided by Hwa Yong (Hong Se Na) in order to save the crowned prince Lee Gak (Park Yoochun). Prior to the event, the princess (Hong Se Na) followed her father’s orders to put poison on the dried persimmons. Bu Yong catches on to the situation and asks Lee Gak to award him with the persimmons for solving Lee Gak’s riddle.
Bu Yong eats the poisoned persimmons and saves Lee Gak’s life. The reason Bu Yong ate the persimmons without revealing the evil plot was because she knew the danger her family could face if she revealed the truth.
Lee Gak finds a letter written by Bu Yong. Before her death, Bu Yong wrote ‘There are some good things about death. I can say something that I have kept secret all my life. I loved you. I was fond of you from the very beginning. I’ll live even in death, I’ll die even with life, even after hundreds of year, I will love you.’
From then on, Lee Gak cannot help but remember Park Ha (Han Ji Min) even after 300 years have passed. Lee Gak sheds tears remembering the members that had happened. Lee Gak writes a letter to Park Ha, ‘Park Ha, I arrived safely. How are you? If you could read this letter, it must be 300 years from now,’ and hid the letter under a pillar in the palace.
Park Ha finds the letter 300 years later in the present time and longs for the love of her life Lee Gak.
