I've been trying to remember this one manhwa I've read before. I have zero recollection about the storyline but what I do remember is the mc is a girl got adopted into a ducal(?) family and some time in the story, she got a pet tiger.
The only VERY SPECIFIC scene I remember is the dad leaned to a door frame while wearing a red bathrobe/sleepwear with his chest showing (｡・//ε//・｡)
That's the only thing I remember. Please help this degenerate girl remember what manhwa is it (￣∇￣")
