Adrian Xu and the League of Schools Chapter 51

Nathan Shao didn't know much about his classmates, but he often helped teachers of various subjects to mark homework and calculate scores. He could remember almost all the names he had encountered. If he remembered correctly, there should be no one named Kang Kai in the entire second grade group.

And if it's someone from school, they won't say "Come over quickly".

Then there is only one possibility left, that the person named Kang Kai in Adrian Xu’s mobile phone contact list is from outside the school.

Should be friends.

In the chat box, the line "typing" next to the contact flashes intermittently.
