- Description from Novelupdates

An engagement paper to lock one’s destiny. With her family facing financial difficulties, she marries into the family of the richest man in Qingzhou as his wife. Her Mother-In-Law’s doubtfulness; her husband’s childhood sweetheart; her mean elder sister-in-law; her narrow-minded younger sister-in-law… Being inferior, Sang Wan withdraws without a choice. As time passed, she ended up being lonely and died tragically.

The moment the little tyrant of the nobles, Roel Ascart, saw his stepsister, he recalled his memories. He realized that he was in the world of a gal game he played in his previous life. To make things worse, he was the greatest villain in the common route of the game!

“I’ll be killed by the main character and the four capture targets ten years from now. Is there still any hope for me?”

Just thinking about the fearsome glints of those sharp swords those beautiful capture targets held in their hands, Roel couldn’t help but tremble in fear.

Till a voice finally sounded in his head.
