I Choose The Heroine's Route

Shana Monique has only one wish – to die and be reborn. Who would've thought it would actually be granted? Then she faced a crisis, she was reincarnated as the villainess whose ending always end up with 'execution'. With survival in mind, she set her sights on the calm heroine. She made 1 main plan and 2 backup plans with Plan C being the main one. Plan A; Runaway. Plan B; Seduce one of the capture targets. Plan C; Befriend the heroine. But it's strange. The heroine is acting weird? The development is wrong?
