Vol 4: Ch 193 - Too Much Coincidence
After hearing that question from her Mom, Na doesn't know if she's going to be sad or be happy.
Na: Mom, am I really your daughter or not?
Annie: Of course you are and I just ask you the same one and you must put yourself if you're in their shoes so that you can relate what kind of nonsense your question to them just now.
Na: I don't really know if I'm really your daughter or Rei is your daughter.
Annie: Then If I have a daughter like your friend Na then why not, at least she is sensible enough and not a spoiled brat just like you.
Na : (Got speechless and regret that she said that one to her Mother)
