Alpha Damien's Breeder: The first night - Chapter 1: The rejection

Before her rebirth, Song Ran lived a lone and miserable life. Her innocence and naiveness cost her fortune. Her family assets was wasted by the stepmother, and her man stolen by her very best friend. After she was reborn, having the scales fallen from her eyes, Song Ran learned from her mistakes. The first thing she needed to do was ride on the coattail of her man with a promissing future, Mr. Gu.

As tragedy befalls Xin Siyue, she soon finds herself transmigrated into a novel world as a character. To her disappointment, she became the villainess who obsessively chased after the male protagonist while scheming to tear apart his relationship with his beloved.

To avoid her death route, Xin Siyue carefully avoided the male and female protagonists at every turn. Instead, she went off on her own to enjoy life. But somewhere along the way, she made a mistake– the male protagonist took notice of her!

Xin Siyue’s eyes teared up as she was being kissed in Chen Sinan’s arms. ‘No! This wasn’t in the plot!’
