Actually, after Sarah Sullivan sent Brightan back, he didn't really fall asleep.
He still wanted to be with Aunt Sarah.
So he followed up and happened to witness the incident.
He silently drew it out.
Brightan didn't allow anyone to bully Aunt Sarah.
Regardless of whether Aunt Sarah was standing up for him or not, he would protect her.
And little Bun, of course, also heard those maids belittling him.
But at his young age, he didn't care and didn't feel hurt either.
As long as he knew he wasn't a fool, that was enough.
What others thought and said had nothing to do with him.
...
"Brightan, you're amazing, Auntie loves you!"
Sarah Sullivan's face broke into a genuine smile.
She was happy not because her injustice had been cleared.
Because she didn't care about those accusations in the first place.
At worst, they could part ways, what could they do to her?
She was happy because little Bun had such talent.
Happy because of little Bun's support for her.
