I'm not sure what it is about this drama but i keep getting feelings of deja-vu as i watch it and it feels like there's maybe something i've seen before with a similar plot but i can't remember. 

Anyone know of any dramas that are similar (either in plot or in vibe)? I'm especially getting deja-vu during the courtyard scenes - the setup  of scenery seems familiar and also similar feelings during the bio-mom and daughter's interactions.

I know this type of plot is makjang 101 but i'll take any and all suggestions in case it may. be what i'm looking for
