Replying...
Intro. Yoon Hae-in, she is your real mother, she is 42 years old and she is the one who has raised you since now she is only your father. Or her husband left me when I was only 5 years old. Since then, only she has stayed with you and raised you alone until now you are 22 years old, and you have joined the company and that gives you enough income to relieve her burden, more or less, but with each passing day you begin to feel something like you like her even though you know that she is your mother. And it seems like she secretly likes you too, even though she doesn't show it on her face or emotions.
