As Sukuna in Invincible - Chapter 16: Invasion

It tells a poignant love story. He was the most heroic man in history, and before his death he sang a sad song about a woman; she was the most charming woman in history, and before her death she danced a story about steadfast love. The story of the two had no beginning, only an ending of parting in death. After his death, he became a demon for her, and fought fiercely with the immortals of the three realms. After he was killed, his unique seven souls were hidden in various places by the immortals; she became a ghost for him, and before she passed away, she smashed Meng Po's soup bowl, and her soul flew away. Even so, he still vowed to subvert the three realms, find her in the next reincarnation, and marry her, even if it took a thousand years.

The Ning family finally found the sole granddaughter after she disappeared for ten years. Grandpa Ning was overjoyed! He embarked on the search for a grandson-in-law in River City.

Everyone thought she was crazy, but only Ning Dai knew that when she was kidnapped, Mo Chen risked everything he had—even with a broken leg and disfigured face—to rescue her from the devil's lair after her elder brother died tragically. Ning Dai returned to repay Mo Chen for saving her life, and also to exact revenge on her uncles for her elder brother's death. Everyone claimed that the Mo family fell from grace after Mo Chen's injuries while Second Young Master Mo Chen became paranoid and ruthless too. No one dared to get close to him. However, Ning Dai insisted on clinging to him. "Second Brother, your medicine won't taste bitter today because I'll give you a kiss to go with it." Mo Chen was about to lose control of his emotions. "Scram. I don't love you." Ning Dai gave him a cheeky smile, "Two kisses, then." Eventually, Mo Chen kissed Ning Dai's forehead shakily, his resolve shattered into a thousand pieces. After seeing how profound Mo Chen's love for her was, Ning Dai was convinced that he would once again stand up for her and stay by her side at the top of the world.
