Seven and little nine had two swimming lessons every month. Usually, rich kids would hire people to teach their children.
However, Gu Jue felt that it was necessary for the two of them to be like other children. They had to teach together and interact more with different children. This way, they would not be antisocial and would know how to get along with other children. They would not be afraid of strangers.
Little Seven's personality was more extroverted, so she would play well wherever she went, and she could also play crazily with other children.
However, little 9th couldn't do that. His personality was more aloof because his mysophobia was already showing at this time. Therefore, he didn't want to go to crowded places.
She also didn't want to play with unfamiliar children.
Therefore, Gu Jue spent more energy on him.
On the way to the swimming pool, little seven wanted to hold little Nine's hand, but little nine refused to let him hold it.
