Lee Minho "Minsung"

In ancient Japan, there were demon slayers, who killed and fought the various demons that appeared to harm humans. One of those demons was Minho, who, blinded by his desire for the Shikon Jewel, a jewel that granted infinite power to any demon, went to the village of Irishima, where he fell in love with a human named Kikyo, who was the guardian of the Jewel. However, a demon impersonated Minho and snatched her away, causing Kikyo to hate Minho and seal him in a tree for 50 years, ultimately leading to her death. After those 50 years, Jisung, a teenager who had a well next to his house, accidentally fell in and was transported to ancient Japan. When he arrived, he saw everything covered in trees and small villages, and he saw Minho asleep in a tree with a kind of spiritual seal. Before he could break the seal, a serpent demon appeared to kill him. Jisung backed away and saw Minho wake up and tell him to break the seal to protect him.
