Why would Xiaoen call the caller auntie but the 'aunt' told her that she gv birth to her too? Biologically the caller is the Xiaoen's mom?. Im confuse

A little confusing yes, but it seems that xiaoen was put up for adoption by her bio mom (the caller) & subsequently adopted by another family in peach town. Im assuming she doesnt hv a good relationship w her bio mother and so she wldnt refer to her as her mother. also "auntie" may just be xiaoen using chinese honorifics to refer to the caller..
Im so happy Mian finally tell Banwoo about her feeling towards Haegu and how she put Haegu's happiness above herself. The look on Banwoo's face was satisfying. You are a family too Banwoo, but like a very distant cousin etc. Get a grip!!.
