Does my new coworker like me? How to avoid mess at work?

Met a few new coworkers last week. On second day, I had instinct that one of them probably likes me. In a gathering, only he and I happened to be together and he locked eyes with me and I instantly looked down. Then he told me he is going to go sit with another coworker. After a minute, I joined them and sat next to him. He turned his head to look at me twice and no one was even talking that moment. I also noticed him looking at me many times after that. He showed care towards me and not other female coworkers. I could be wrong and he might be in general a nice person.
He asked questions that were about if I was thinking of going back to my home country or decided to settle here (I am immigrant by the way).

I had decided I will not think about him but after I’m back from my work trip, I am :-/ I’m feeling like a teenager writing this :-(

I will work with him remotely and meet every few months in person. From what I got to know about him, I like him. I also know that I want to avoid any office drama.

question 1- do guys act like how he did the first time of meeting a girl?

Question 2- how to handle what comes next?
