Familial Centric Ending

Modern C-dramas with contract relationships often tend to have scheming Male lead and Utterly spineless Female Lead, this one although with a cold & smart ML and naive & cheerful FL neither has elaborate schemes to make the Contract last nor extensive misunderstanding segments to keep the drama going.

If Misunderstandings did exist, they didn't last long. Additionally, ML knows where to draw the line (to prevent misunderstandings) which is applauded. Our FL is brazen and bold too, with taking initiatives in the relationship.
Side characters though lackluster but don't bother.

The ending is family-first oriented with giving up opportunities that can be a bit off-putting but everything else is cute and sweet.
