Romance Drama Where the ML Addresses the FL Affectionately from Early On?

Please recommend romance dramas where the ML shows his affection for the FL by refers to her with an affectionate term (honey, wife, wifey, missus, etc.) earlier than he would necessarily be entitled to use that term based on his actual relationship with the FL. For example: My Fated Boy, Love O2O, and I Need Romance 3. 

Faith - kind of fits. The term ML uses to call FL apparently has different meanings in different contexts and can have a romantic connotation. In this case, it grows to become one.
