“Sometimes it's about remembering and never forgiving.”Jane Devold, the only daughter of the CEO of one of the most successful tech companies in the country, grew up to be a seemingly happy and spoiled young woman, despite her stuttering and fragile condition.However, her rich and elegant way of living ends in a heartbeat when her father goes missing, leaving Jane alone and with an enormous debt on her hands.That's when she reunites with Vernon Lin, her strange and intimidating senior from college, who claims to be the new owner of her father's company and promises to resolve her financial issues if she agrees to marry him.His offer seems harmless, and Jane accepts his helping hand only to realize that Vernon's intentions are not so pure, and his personality is still miles away from that of a knight in shining armor.But what really does feed Vernon's unhealthy obsession with Jane? Whether it's his desire for revenge, his own twisted way of teaching the spoiled young woman how the real life works, or unresolved complicated feelings, he still succeeds in turning Jane's life into a living hell.Until he realizes that without her, his own life is hell, too.

On the wedding night, she was tied to his bed.

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
