Im pretty sure what happened is the dad was selling her and she left with out her kid and then found a new family, but when that family found out what happened with hyesung they like dropped her or something like that so sheβs all alone now. At least that what i think i remember. It been a while since a I read the first story

I really dislike hyesung mom .
But I'm also curious to know about her situation, that byul pointed out " you don't even know her situation"
