Genre: Jousei (or shoujo), smut.

A manga/manhwa at least before 2010?
Main girl got into an accident, her home caught a fire, which left a big scar on her thigh. She's still beautiful but traumatized. She met a rich guy who has a little son. She moved to his villa/house...as a babysitter maybe? I can't remember what happened afterwards but after some drama they made love and became a happy family in the end with the guy's son.

I thought it was Kizuato made Aishite but the one I'm looking for is more angsty and drama-ish?

Honestly it's not that good but it was my first smut by accident and I'm feeling nostalgic lol
