Because Mi-Ok knows that being different (not being loved by her parents like a child normally should. She felt insecure to the point of not wanting to meet her friends because she felt she is not normal) made her feel so she doesn't want Mr.Kwon to feel the same thing
I think that's the correlation (?)
But still, it's wrong for her to meddle in Mr. Kwon's relationship
Is it just my brain cells not connecting or what?
1) Reason: not loved by parents..
2) Conlusion: meddle with Mr Kwon's relationship..? Σ(っ°Д °;)っ
