After the Villain's Darkening Value Exploded, I Was Forced to Love Him

[Two male protagonists + quick wear + blackening + forced love + double cleanliness + 1∨1] Gu Ningye was tragically selected by the blackened villain system. Only when the villain's blackened value reaches 100% can he complete the mission and return to his original world. But how can we make the blackening value increase faster? Should he join the protagonist group and fight against the villain at every turn, be a troll and drag the villain down secretly, or be an evil pervert to disgust the villain? No, neither! The fastest way, of course, is to give him hope and then shatter it, causing him to fall completely into the abyss of despair. Therefore, Gu Ningye played the role of the villain's good brother conscientiously, but when he won the villain's trust, he chose to betray him, giving him a serious emotional blow. In this way, Gu Ningye finally completed the tasks in all the worlds, but was informed by the system that the villain's blackening value was off the charts, and each small world could not bear this energy and was about to collapse. Only by wearing it back and reducing the villain's darkening value can he truly complete the mission and return home. Gu Ningye: ... Isn't this over? ! ! The Black Demon Lord sealed his cultivation and imprisoned him: Senior brother, you owe me, and you will be punished to only look at me for the rest of your life. The poor little man who picked it up took off his disguise and revealed his true face: Brother, you forced me to do this. The powerful Enigma caressed his glands: From now on, everything about you is under my control.
