Deep Inside

Inside every lived soul, there is a precious seed for reincarnation into next life. Koo Ryeon once had her seed removed when she was sentenced to Hell 400 years ago. She finally had it back, reinstated as a lived soul. Thereafter, Park Joong-gil and she had good time as husband and wife in Jumadeung.
At the end of the story "Metamorphosis", Hades divorced Alice. To make up for her loss, Alice had made Hades step down from the head of Hell. She took care of Hell. Inexperienced she was, there were riots in Hell. The imprisoned ghosts were escaping. A few stole their seeds, running to Jumadeung, looking for the gate of reincarnation. Grim reapers from the Hell and Jumadeung were catching these ghosts back. Fate was brutal to Park Joong-gil. Both he and the ghost fell into the gate of reincarnation, Joong-gil accidentally reincarnated into next life, was born the only child, namely Li Yuan, of a middle aged parents.
Hades had told Park Joong-gil before, that Alice might take revenge against Ryeon. Therefore the couple had secretly transferred Ryeon's seed into the Joong-gil's soul. After Ryeon lost Joong-gil, Alice wanted to remove Ryeon's seed. When she found there was none, she exerted her strongest power to exile her out of Jumadeung, to Land of Living. To be exact, Ryeon was not reincarnated, but became Qin Yue, a patient in coma for over 20 years.
It is year of 2055, when Li Yuan (carrying the seeds of Joong-gil's soul and that of Ryeon ) and Qin Yue (the body which carries Ryeon's soul) meet to start their relationship, but in an era when humanity and true love is easily shaken.
