I can shut my brain off and just enjoy this drama for the most part. I do find it really odd that the child randomly appears as if the stork just dropped her off a little late. After the first episode no one seems concerned about it. They just accept that she will live with them. We have no backstory or clues....No one asked her about her past, no DNA test, or so far the police don't seem to be involved. It's kinda weird. She's not a stray cat.
