In their past life, Hyo-un made the orb but was too late to give to Taehyuk since he died beforehand. After reborn, Taehyuk once again encountered death while searching for Hyo-un cure. When Hyo-un found him in the mountain he gave Taehyuk the orb knowing it will be too late if he still hesitated like in the past. However, Taehyuk was badly injured. He was in the middle of life and death. Hyo-un orb try to prevent taehyuk from crossing to the underworld. I hope next chapter would be a happy ending since I cannot stand how worst Hyo-un had been thru..... pls give my baby dragon happiness... It's a torture to see Hyo-un neverending tragic love.
