Paul definitely didn't want to go with Mie and his mother, no matter how much they persuaded him to go. He accepts that he is bored at home reading books alone and does not want to go to the mall to go for a walk with them. Before, he thought that choosing his mother to choose the clothes for sure was a very happy feeling, but now he has thought again. You don't have to be happy about this.
Sarah and Mie still tried to say a few more words before leaving to convince Paul to change his mind, but the boy persisted with his decision. So Sarah and Mie didn't say another word. When going to the car, the butler did not see Paul accompanying him, only saw his grandson with Sarah. He was stunned, felt awkward, so he spoke up.
"Miss Sarah, if Paul doesn't want to go then let Mie stay at home and play with Paul. There's no need to go, she won't go with you."
