The Vicious Female Supporting Role Is Undisputed

I am a vicious female supporting character who fell in love with my best friend's boyfriend. In order to successfully rise to the top, I tricked my best friend into studying abroad to give myself a chance to rise to the top. I drove my best friend crazy, made her suffer from depression, and almost made her commit suicide by slitting her wrists without saving her. Everyone thought I should break up with my boyfriend and give him back to my best friend! No one knew that when Shen Heng and I were together, they didn't know that he was Zhai Zhenzhen's ex-boyfriend. Intention: Beautiful alone
