Giấc_Mơ_Qua You had a crush on her back then didn't you? 
She too did have a crush on me and also gave me a love letter during our high school years.
But one of my best friends and one of my childhood friends also had a crush on her back then, and I had promised them I would not take part in that so I said no.
Few years later, during college time, not long after she broke up with her boyfriend (another of my friends), we went out with our group of friends. She once more gave me hints, even tried to hug me when we got a little bit drunk. But I only smiled and did not make any moves.
Now she about to marry another friend of mine...
haiz, I've never been wises.
Come to think about it, it's kinda weird how all the guys above are 4 different guys, and they're all my friends haha.
haha.
