Lost Track of Time (2022)

- FL was killed by those persons whom she trusted.
- FL reborns again to take her revenge.
- Pairs up with ML whom she ignored in previous life.
- Gradually fall in love.

Literally the same premises. I read the synopsis on Viki and thought oh is this the one with Zhang ling he?

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both FLs are betrayed and murdered by the man they love. They then get a second chance at life (time travel vs. their soul entering someone else's body) and set out for revenge against that man. Along the way they become involved with that man's kind-hearted brother.

Same time travel "reset" theme where FL was mysteriously given a second chance to relive her past and change her fate.
