"A-Yeong I'm very disappointed in you. I'm disappointed in you for trying to embarrass your sister and for what you did to her in the past. You wanted the company, I hope you enjoy it, just as she's actually enjoying her job. And for your sake I hope grandfather will still be as proud of you when he hears what for what you did to Hei-Ran back then." She wouldn't have known that A-Yeong was the one behind it had she not overheard them talking. They had all ran to the kitchen when they heard Hei-Ran's voice, but they were surprised when they heard what Hei-Ran had said, they thought A-Yeong was going to deny it but she didn't.
Mother Su had no intention of exposing Hei-Ran's lie, as a matter of fact she was going to encourage them into playing on with their lies she wanted to see how they could go with it, but when A-Yeong tried to embarrass her daughter in front of the whole family she decided to turn it her advantage.
"Aunty!" A-Yeong snapped.
