Search Results: first impression on people

I like this guy & we live somewhat close to each other & we're on the same bus. At school, whenever we get off, he'll always walk a different path/sidewalk (to the doors) even though both paths/sidewalks meet up at the same spot. Also, whenever these guys are around (friends?) when me and him are near each other, they'll always call out his nickname or tease him about taking his "shortcut".
Usually he walks by himself whenever we walk pass or next to each other & he'll look at his phone or down at the ground. One time I asked my friend to look at him while we walked passed him so that she could see what he'd do when him & I walk past each other. She said that he avoided eye contact & looked at the ground, towards our feet & that he looked pissed or upset. At first I thought that was a bad sign. But I did research & someone said that (shy) guys tend to look angry when walking by someone they like (something about impressions & low confidence)
Yet, we do happen to make eye contact every once in a while & I used to catch him staring at me when we used to have the same class together.
Also, one time I was taking pictures at his basketball game for the school's website. I know he saw me bc his basketball during warm ups accidentally came my way, so I know he saw me with my camera. At one point, I took a really cool action shot of him & uploaded it to the website. A few weeks later, he took a screenshot of it & used it as his profile picture for his social media account (s). Not sure if that means anything.
He never talks to me & I don't even think he knows my name. He may be shy but he has a lot of friends (boys & girls) & talks to a lot of people. It's just when we're near each other or in the same room, I get this weird, awkward vibe from him. I asked someone what they thought & they said he may be interested but is shy.
What do you think? Is he interested or not? I have this plan I want to do so I need to know if he's interested before I do it.
