In these three days, things have happened, so can anyone please read this and tell me what you think about it? Btw this guy is a very outgoing guy~

On Tuesday, it was concert day, me and him belong to the same class, so we performed together...
We were waiting to perform, and he looked at me a few times
He was sitting opposite to me in the performance, and he looked at me a few times in between songs
After the performance, we went back to our room and he stared at me
He was near me and his friend went to talk to him and they looked at me at the same time
He took a chair and sat opposite to me in the room twice
When I waved and said hi and smiled at him, he did the same for a long time
I didn't sit opposite to him in the second performance, he looked at me after he sat down

On Wednesday, it was also concert day~
We were waiting to perform, and he looked at me a few times
He was sitting opposite to me in the performance and he looked at me a few times in between songs
After the performance, we went back to our room and he looked at me a few times
In the night concert~
When I went into the room, he looked at me and waved and smiled(he always hugs or fist bumps people instead of waves)
He looked at me a few times before the performance
He stared at me for a long time before we started playing
After the show, me and a friend went to the balcony to watch the show~
He was sitting at the other side of the balcony, but all of a sudden he walked to my side and waved at me and sat right in front of me(this has happened before)
All of a sudden he turned around and talked to me about random things like "Are those flashlights annoying?" and "Are you in the hallellujah chorus?"(this has happened before)
When I said I was gonna play in the hallellujah chorus, which was the last performance, he stayed behind and watched it

On Thursday it was regular school day~
I waved and smiled at him, but he stood up and kinda ignored me... Then he immediately waved right in front of me and said hi as he passed by me
He stood right next to me when I was texting and kinda looked at it
He stood right next to me and kinda looked at me like he wanted to talk to me
He wore a hat and stood right next to me and looked at us
He hugged a guy from behind and looked at me
He was always walking around me or next to the piano, which was near me
He looked at me before I left, like he was saying "Merry Christmas!" to me
