New Crush

Hi,everyone! Recently, I discovered that I like a guy in my CCA and he is my junior. Is it weird to like a junior who is younger than me by 1 year old? He is not that really cute guy but I can tell that he has a super nice and patient personality and I can tell that he is a really nice guy. Hence, I have a crush on him. I feel nervous when im around him and I can sense that I am doing weird stuff as I cant control myself. He makes me feel that..is it a sign of liking? He is also my instrumentalist and he plays the piano super well. Should I continue this crush? I feel that its a bit awkward.
