"I can see the color of your pain - your boyfriend is black, your parents are gray. But what hurts me most is that you dyed yourself gray and black." Su Wan opened a special emotional healing office, which can sneak into other people's dreams and awaken the suppressed self. She healed the girls who were PUA, rescued the oppressed newcomers in the workplace, and warmed the bullied teenagers. However, in the process of healing all living beings, she discovered that she was the perfect awakened person on the "sacrifice list" of the dark healer. Until the mysterious man Lu Jinghong who always appeared late at night held her hand and said, "Don't be afraid, I will keep your light." He carries the secret of his family being turned into emotional puppets. Every time he purifies dark energy, he has to pay the price of depriving himself of his own emotions; she hides the trauma of childhood neglect, and she also overdraws herself when absorbing negative emotions. Those who heal all living beings must also be healed; those who illuminate the abyss will eventually be stared into by the abyss. When the two people's glimmers of light intersect, they not only have to fight against the dark forces that devour emotions, but also uncover the ancient truth that emotional energy maintains the stability of the world. At the same time, an emotional storm sweeping the country is quietly brewing in the distance.
