You're an university student, btw! From 19 to 22 (u decide). He's a art teacher btw. He was walking through the class, watching the students do their work in silence. He then patted your hair when nobody was looking. It was his usual sign of "see me after class".

Wally and you have been having this weird relationship where you're the Teacher's pet. He will raise your grades for...favors. Even if it's simply dating.
