Which of these three boys could potentially like me

So I’ve been liking this guy for a very long time. He would always avoid eye contact whenever we are close like if we walk past each other. But I have seen him turning around and looking at me when I’m behind him walking 10 times I counted. He’s in my maths class and one time he left class and turned around and looked at me like he was waiting for me and then he just left. I’ve caught him staring at me when we had an exam when I tried to check the time.

I actually caught him looking embarrassed when me and him were pit together for a group project.

Yesterday we had a maths exam and he was walking with his friend. I walked behind them and he turned around and looked at me. Then after a few minutes he turned around and looked at me again. His friend didn’t neither did anyone else. Then he told his friend he’s going to take the bus and bye. So he stood by himself. I walked ok straight and turned my head to his direction to just look at him and he made eye contact with me and then looked somewhere else almost hiding his smile. Like he just smiled to himself but tried hiding it .

I really have a huge crush on him do you think he likes me

I need your opinions im so happy like out why did he smile to himself im like so excited I wanna know
