Six days later which happens to be on Friday, Areum and her mother finally discovers that Kim Hyejin was truly Kim Dong Hyun's daughter, and that her mother was Park Hayoon. Actually, it was Kim Ara that made the guess and confronted her brother about it, and the latter didn't know when he said that her guess was right that he discovered that it was too late.
"Ara, you better stay put and don't cause any trouble with this information." Kim Dong Hyun warned.
"Of course I know what to do." Kim Ara had said before walking away only to tell her daughter about it after going to her bedroom to find her.
"I knew that staying in this house will help us find information about her." Areum said with a confident smile.
"I'm really surprised that her biological mother has been by her side all these while and nobody found out about it. I don't think the Wang family knows about this, should we tell them about it?" Kim Ara suggested.
