I placed a lot of Tags that has mature content as this novel will be full of spicy lemons. But, of course, it will have plot as writing too much lemons is mind tiring. Have a good time reading it. Also, if you see mistakes at the beginning, don't worry, it becomes better as you read. If you understand me.( ͡° ͜ʖ ͡°) All the rights of the works I may use as reference are from the respective Authors, with the exception of my OCs. Also English is my third language, so forgive me if you see many mistakes or chronological errors.

I've left you some real estate and cash. It's enough for you to live comfortably for the rest of your life." Yan Xi revealed a confident smile. "I've thought it through. Zhang Ming stabbed your men with a knife. You should hand this matter over to the law. I won't interfere anymore." The surprise that Yan Xi's change brought to Gu Shen did not end there. After that, she tore off the mask of her hypocritical best friend and calmly dealt with her scheming family members. She personally treated Gu Shen's chronic illness for many years. Bit by bit, she managed to shock everyone around her who was once prejudiced against her.
