At times like this, with their mother absent, they should have been easy to approach.
But their father told them not to readily accept her kindness, because their mother wouldn't like it.
So they haven't said much, and when they see Su Han, they ignore her.
Yu Ze, being no longer a child, is fully aware of Su Han's intentions.
The younger brother is still too young to understand, but he listens to his big brother.
If his brother says not to like her, then he won't, and Su Han probably never expected Yu Chen had been brainwashed by Yu Ze.
This outcome was unanimously agreed upon by the Chu father and sons, so no matter how many times Su Han comes, it won't work.
Because they won't like her, so her coming is futile.
However, seeing her eagerness, Yu Chen feels he should at least respond.
