As the full name of the trope suggests  "chasing the wife in the crematorium" Basically means the type of stories where the ML first treats the MC badly, ab*ses and/or ignores and causes a lot of suffering. And then, when the MC loses his love for the ML and leaves or dies, the ML regrets and repents, suffers, grovels and works hard to earn the MC back. 

-This list may include transmigration,resurrection,time travel.

-All these novels have a happy ending .
