Shen Yi, who was young, rescued Chu Chen who was bullied. Chu Chen had not lived a good life since he was born, but Shen Yi's heart was like a ray of light. Shen Yi promised to marry Chu Chen in the future, but Chu Chen left without saying goodbye.
Ten years later, Shen Yi came to look for Chu Chen with the red rope chain that Chu Chen had given him when he was a child. He thought about practicing while traveling to the ends of the earth to look for Chu Chen.
But Shen Yi actually became a master and apprentice with Chu Chen, but Shen Yi didn't recognize him at all because the gap between Chu Chen now and the smiling boy back then was too big, and Chu Chen didn't want to implicate his own hatred on the boy he loved, so he hid that he was the boy back then.
But their lives were destined to end from the beginning, and they could not escape their fate after all...
