A wedding took place, and the richest man of Shencheng married a woman notorious for her bad reputation.Ning Guiwan was known among the upper class as a calamity—tormenting her sisters, causing her mother's death, leading an unseemly private life, despised by her father, and cast abroad to fend for herself.Four years later, she returned and directly took hold of Shencheng's most esteemed man's arm to enter into marriage, leaving the whole city in shock.However, amidst the doubts, Ning Guiwan presented a post-marriage agreement to Quan Yu, with the last clause reading: beyond cooperation, there shall be no involvement with each other.Quan Yu pinched the girl's waist, his lips curving into a smile, “You start the game, but I decide how to play it.”……Everyone said that Ning Guiwan, relying on the favor of the Quan Family's old matriarch, forced Quan Yu to marry her; otherwise, how could a man with such sound principles fancy a woman not only beneath his station but also with a scandalous past?But those who knew the truth shook their heads. Sound principles? Nonexistent. To get his wife, Mr. Quan resorted to all kinds of dirty tricks, even deceiving the old matriarch, yet Mrs. Quan, with her cold exterior and hard heart, married him but refused to love him.Until one day, Mr. Quan accidentally got injured, causing Mrs. Quan to frown.Then—“It's terrible, Mrs. Quan, the master has injured his arm, please come back and see him!”“It's terrible, Mrs. Quan, the master has injured his leg, please come back and see him!”“It's terrible, Mrs. Quan, the master...”“What happened again?”“The master says he's sick, please come back and see him!”“What sickness?”“The master says it's... lovesickness...”“……”[A pampering story, sweet to the extreme]

“I curse you to never die in peace!”

Thus, Shang Ke started a never-ending (forced) cycle of constantly throwing away his miserable life.

He would always show himself as a martyr while letting others cry over his death.

It was because of a woman’s curse that Shang Ke was hit by a car and turned into a human vegetable. This led to him becoming bound by an unlucky system in which he was cursed to die. The most unfortunate part was that he never cheated on anyone’s feelings. The reason for why he was cursed by a woman was because of a guy named Qi Chen. Qi Chen was a ladies man, and he would always use Shang Ke as an excuse to break up with any woman that he was with. As a result, Shang Ke was always blamed for the breakups. Since then, the main character could only be forced to cross into different worlds. He would thus experience for himself, the hero’s “thrill”.
