I don't know So Hyang on a personal level and I might never have the opportunity, but good for her for writing her own narrative.
All she wanted to do was keep her life private because she should have the space to do so, but naturally the public wanted to know about her personal life.
I guess the public saw her not with her husband of 25 years so fans got curious.
She said that after watching K-Pop Demon Hunters, she felt inspired to let fans know that she had been separated from her husband for 2 years. I also loved that she mentioned that rumors can be hurtful.
