Im having computers problems but the one and only computer tech is starting to weird me out

He bought me coffee once, despite me politely deciding repeatedly.

I noticed candy being left on my desk but assumed that a student somehow left their candy on my desk.

Soon after he left Friday, I noticed that same candy on my desk.

Last time he came, he fixed my issue but continued to just sit there. I was like "is it fixed "?

Him: yes, I'm just hiding out in your room if you don't mind.

I ignored him and continued working on things in my room (away from him)

I'm gonna address it next time.
