Every time Shen Qingdu "accidentally dies" next to Fu Siheng,
They will all be reborn at the key point where they met Fu Siheng.
She found herself trapped in the cycle of (loving him → being hurt by him → death → rebirth)
After her seventh rebirth, she decided not to love him anymore
It's about "acting" a perfect escape drama
Let Fu Siheng remember her forever and be in pain
The first six times, I loved you with my life, and the seventh time I used 'death' to make you love me.
