maybe she ran from home, or her stepmother chase her away
Yes, it is possible. However, it is odd that her father had gathered all these elements against her (the tax evasion, etc.), and yet did not act at the time. This is, in my opinion, lacking in the logic department. But this is a drama. So I won't complain much, lol.
I loved the drama. However, there are still plot holes. I don't get the relationship with the stepmother. Why was the mother dragged out of the house. This was never addressed. In the initial timeline, what could explain Chung Ah's sudden poverty? I'd have loved to know about this arc as well as, to me, it appears the father was never against her, even if absent.
But it was a happy ride overall <3
