Am I overthinking or does my male colleague like me?

I have a question about something that recently happened at work with a male colleague.

I normally have lunch at the cafeteria with all the Korean homeroom teachers and other staff. I work for a Christian Middle School and there are a few male Korean teachers there. This one time the sub teacher (female) was asking me if I was single and I said I was, behind her there were male Korean teachers and they overheard this.

One day I dish up as usual and sit in one of the desks with my colleague. I notice two male teachers coming to sit by me and my colleague and then the other one sits next to me. The one sitting next to me was very close and would brush his shoulders against mine and it seemed like it was unintentional, but it definitely intentional maybe to get a reaction from me or a signal that I’m interested. I acted very normal like this wasn’t a big deal but deep down I was nervous (I had been eyeing him as well and found him to be attractive). This happened a few times of us eating until I was done and left. I felt like the male colleagues were his wingmen and he was trying to get close to me. It felt like he wanted to say something but was too scared.

Ever since that moment this man started to greet me and wave whenever he’d see me. He’s so friendly and smiles all the time. I found this to be weird because I’ve been working there for a few months and he never did anything before this occurrence.

I also had a student (16) in my favorite class randomly ask me, if I had a husband I didn’t answer the first time and the same kid asked again. I found it to be strange because he wasn’t a kid that conversed with me often like the other students. I think he was told to ask me.

I think he likes me but I could be reading too much into it. I like him too but I don’t know how to show him, since this is all happening at work. I’m 27 and he’s 34.

What do you think? I don’t know if he’s interest in me is genuine or just looking for fun.
