It happened to me in the past, when I was in Sec 1, I had this
huge crush on this girl. My best guy friend was close to her, and I
somehow suspect they are more than just friends. Everytime I ask
him, he would say, 'No lah, i like someone else leh.'
A few years later, I found out from the girl that my BEST FRIEND
had admitted to her that he liked her. Ever though they didn't get
together in the end, i was pissed off enough to cut him out from my
life. I was pissed not because he liked her, but because he always
act like he didn't like her at all, even though he did, and when I
ask him, he always deny it.
