I met this guy online. Why is he asking me do is there any guy I like or am interested in? Why is he asking if my guy friend is my boyfriend or not?

I met this guy online online. We have known for a couple of months and I found he is easygoing and playful person. He likes to ask me do is there any guy I like or am interested in at university or during my internship. He also likes to respond to my ig and likes to tease me.

Today I posted a story of my guy friend in my ig story to congratulate him on his graduation and he asked me if he my boyfriend. What does it mean? Why is he asking if my guy friend is my boyfriend or not?
