Mark was new to the class and Arthur was asked to show Mark the school. Arthur enthusiastically showed and told Mark about everything, since he hadn't had any real friends in the last few years. But he saw the boy following him reluctantly and without interest.

They had a computer science lesson and Arthur sat quietly at his desk and clicked on the screen, all that the teacher demanded. He turned around when he heard his neighbor, Mark, call for help.

Yes, what is it?

Mark said he couldn't figure out what to do. Arthur smiled calmly and got up from his chair, leaning over to Mark and putting his palm on Mark's palm, which was lying on the mouse, and introduced him so showing what to do. Without realizing it, for some reason Arthur sniffed curly black hair and Mark and noted to himself that they smelled like coffee. He mentally slapped himself in the face, realizing that he was invading his personal space and pulled away.

Well...Is that clear?
