Is my neighbour into me?

I am due to move out soon but I don’t know if I should act on this before. I’m very attracted to him but also nervous as hell around him. I’m thinking he’s into me but could I be mistaken? What are the chances I’m over-reading?

1) he would very often adopt a gentle tone and speak softly to me? And also touch my upper arm at times

2) he would sometimes tease me and have this dopey grin on his face while titling his head at me (a very contagious eye-to-eye smile like he thinks I’m super adorable - you know that ‘aww look’ when you give to babies/puppies)

3) we once ran into each other while out and when he realised it - he acknowledged me and then started at me intensely (I was passing him)

4) he seems to come around the common area shirtless a lot when he knows I’m outside - we live in a coliving space. He comes home late night - sees me in the shared space alone and would go into his room and reappear shirtless a few minutes later (on the pretext that he wants water /throw rubbish). I’d be working but it seems like a show for me?

Am I overthinking any of these 4 signs?
Yes you are
No way
Maybe - if so, can you explain?
