The main character is either a transmigrator or has already lived this before. They made mistakes about who to trust, but in this life, there will be face slapping and pampering. 

Specific flavorings I like: 

clever protagonists

the love interests aren't too overbearing, but they should be doting. 

the revenge is generally equal to what the person did to them in the last life. 

it'd be good if there were a few kind family members
