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 productions tell the story of people who 'died by accident', are reincarnated in someone else's body and have to take care of stranger's family.
Both protagonists did some morally questionable deeds in their 'first life' and get a second chance to right their wrongs.

He Fei's wife, Li Mu Zi, disappeared mysteriously during their wedding anniversary trip. While he was searching for Mu Zi, she appeared again out of nowhere, but he insists that the strange woman in front of him is not his wife. Lawyer Chen Mai gets involved in this bizarre case, and more mysteries slowly emerge.

Both shows focus on swapped identity and how leads cope with being forced to live with someone else's family and kids.
