I currently study in a college with a small student population and there's this guy who is not in my year but i do see him and his friends around everyday as the school compund is quite small. We never talked or smiled to each other before, i mostly ignored them. Anyway this continues for about 5 months and one day, when i was walking to class in the corridor, this guy and his friends were there too (just us basically). When i was near them, he came over and said good morning. As i am quite an awkward and shy person, i was basically shocked and so i just smiled at him and walked away.
A few days later, he came and sat with me at my table in the library. We then exchanged our names and talked a little bit with his friends sitting at the next table kidding around.
The next day, he saw me in the library bit didn't come over, but he did said hi <name>. As usual, i acted a little bit too awkward and said a quick hi. When i walked passed him again that day, he said hi <name> too and i basically acted the same way again.
I seriously don't know how should i feel about all these as i honestly have zero experience with guys. Some of my friends tell me he looks like he is interested but this inner coward in me telling me he is just kidding around with me? I am quite confused.
