Is there a chance this guy likes me?

So I met this man in college about the first week I was put in a group with him and some other girl and he had asked for my insta when he got moved to a diff group he mouth and point that he wanted to come back. His friend who is a female but has a boyfriend also asked for my insta. He sees me around campus from time to time and always smiles and waves. On insta I don’t go but my actual name but a nick name that isn’t a common nick name for my name at all it’s actually a nickname for the translated version. And one day I was walking down the stairs and he was walking with some girl, yelled hi and that nick name that was my insta name and then I waited for him come downstairs and I asked him if he just called me that name and he said yeah that he likes it and thinks it’s cute. Whenever class is over he says bye to his two guy friends in the class and then says by to me. We never talk on insta except once I messaged him asking him a question on the final that was approaching, he wasn’t online for 2 hours before I messaged him I checked cuz it was late and I didn’t think he’d answer but he answered within 2 seconds, but he explained what was gonna be on the final and said “dw I think you got this :)” I posted a picture of myself on my story recently and he liked it and he always views my story. I don’t like romanizing anything unless I’m sure they are attracted to me, my friends noticed him always saying him and I brought up the other things since they assume he likes me. If he does should I try befriending him? I don’t know how to start a conversation and the semester is over.

Is there a chance this guy likes me?
