Hi everyone,
Thank you for your comments. Really appreciate it.
After observing him for some time, I realise that he is an insensitive, shy man. I am not saying this to make myself feel better but honestly, I caught him peeping at me. And of cos, he caught me peeping at him too. It is kinda tough to get to know him more cos we are very busy during working hours. Anyway, I have already made the first move to ask him out. Well, I didn't make it sound like a date. I just asked him if he wanted to chill. Unfortunately, he wasn't free but he did mention that we chill another time. It could be his way of rejecting me. What do you guys think? Nevertheless, I was not upset. I am, in fact, happy that I made such a bold move - very unlike me. The ball is in his court now. I can only sit back and observe.
