In the Korean drama Lonely and Brilliant Ghosts, Grandma Sanshen punished Sang Ni and Hellscream because they had a fatalistic relationship. Specifically, Sang Ni was the roaring bride of hell in her last life, but due to the trick of fate, they missed each other on the eve of the wedding, which eventually led to their love becoming a tragedy.

In this reincarnation, Sang Ni becomes a girl who can see ghosts, while Hellscream is cursed and must punish those evil spirits forever. Although they have forgotten each other, their destinies are still closely intertwined.

Grandma Sanshen is the god responsible for protecting mankind. She thinks that the roaring love between Sang Ni and Hell is predestined, so she tries to help them realize each other's happiness. But their love involves the existence of evil spirits, which makes their fate more complicated. So Grandma Sanshen decided to punish them and eliminate the contradiction and pain between them.

Generally speaking, the punishment of the three gods' grandmother is to let Sunny and Hellscream get rid of the entanglement of fate and finally realize their happiness.
