I feel like she was ready to become independent from her mom while dating Golf but her mom played a big role in their (Golf and Kwan) separation. Kwan is her daughter and the bread and butter of the familyAgree. There was that mess last year when she had drama with her sister and Mom about investment money too.
Aum will be like some of those senior veteran actresses that never got married. I feel like she must've missed her chance with someone she really loved in the past.
