Earlier she was angry and didn't do well, just because that rascal turned her day upside down didn't mean she should take it out on others.
Miss. Mina here is like an aunt to her, she is of her aunt's age. The woman isn't young as her. She is an elder to her so just because she is the boss doesn't mean she should disrespect her.
"…Ma'am, you were angry back then so I understand, please don't worry yourself, hmm?" the woman said to her honestly, she has known Esmeralda since she was a child and all those times are enough for her to know how the girl is.
She was the girl's father's secretary since E&F was founded years ago. Robert asked her to help guide his daughter to do her work diligently and she will be here to do just that.
He knew she is capable of helping Esmeralda out that's why he did what he did, she was here with him from the beginning throughout since E&F was founded. She has seen both the bad and good times of the company.
