whether to take him home or not, you should think carefully, especially whether to develop feelings with him. His age is the right time to study, but he didn't put his mind on reading, which is incorrect and there are many uncertainties.

As a child, he hasn't thought things through, and his feelings may change at any time. His parents and family may not support him. I hope you are careful.
