Search Results: act around him

okay, here's some background knowledge. he's 3 years older then me,4 grades higher, and my sister is 2 years older then me and 1 year younger and 2 grades behind from him. lets call him pineapple. so pineapple is much closer to my sister then me. for example, he follows her insta and always gives her second opinions on her photos, and she follows him back and they go through eachothers phones sometimes. but i also noticed her usually doesn't look at my sister a lot, but mostly at me. pineapple also pulled up a picture of himself flexing in the mirror, and me being curious i said 'why are you looking at muscly men bro' and then he said 'thats me-?' and i just looked embarrassingly away. also on my sisters side she always act so.. different around pineapple like bubbly- and with this snob tone. but! pineapple hates when anyone is left alone like he's protective about everyone-. buttt when we went skiing and i was left alone he said' bro why'd (brothers name) leave you he wasn't supposed to' and then i said 'he told me i was too slow' and then pineapple ended up waiting for someones to watch me (this because i have a very bad sense of direction) and i ended up getting lost and getting level 2 frostbite and early stages of hypothermia, and once i told our group that pineapple looked almost surprised and worried. now on new years pineapples buddy, grape, fell asleep on my hand. and pineapple kept like side-eyeing us a bit, and i was confused since i was out of it. also also! we were going to play ghosts in the grave yard but my brother didn't want to team up with me since it was uneven so i ended up going to my room, changing out of my dress and watching squid game, but little did i know they ended going inside and not playing. and im still wondering why! but the more i think about it he likes my sister more then me. is this because of my age gap or is since i shy away a lot? grape also liked my sister whom i look like?

I’m wondering if this guy at work could have a crush on me or at the very least find me attractive. We work in completely different departments so there is minimal chance that our paths would cross in a work related context. Here is a list of his behaviours:

He is the one who started interacting with me. I noticed him gazing at me one day, our eyes met and he smiled at me.

The gazing/smiling happened a few times and he would always be the first to smile, I’d always be the first to look away.

When I eventually said hi to him, he smiled even more

He went through a phase of ignoring me and looking away when stood near me

When we do talk, he is smiling the whole time.
On our first proper interaction, he asked where I work and he said twice that he will have to come and “check it out”. I also told him what time I finish.

My friends said that they saw him walking past our office and staring into our office, ten minutes after I finished.

He acts somewhat awkward/fidgety when we walk and he sometimes backs away/walks away when we talk.

My work friends have noticed the way he looks at me. One saw us talking and she said “if my boyfriend looked like that at another girl, I’d be upset”

I was walking behind my friend and he was walking towards us. He was practically fixated on me and staring at me, then I looked at him, and he smiled at me.

I’ve never seen him talk to other random girls who aren’t in his department.

I’ve noticed that he will mess with his hair if I am nearby.

We sometimes make eye contact from afar.

Yesterday, as I turned around, I saw him looking away quickly which would indicate he was staring at me. And then as I was grabbing some cutlery, I looked up and he was staring at me.

There are some things I find confusing:

I’ve never caught him staring at me and looking at me loads
He never looks at my body, he just stares into my eyes and at my mouth
The whole walking away/backing away when I’m talking to him confuses me

What do you guys think?
