In Korea and Japan, 14th February is the time when sweet young nubile kawaii girls would personally hand make chocolates and give it to the guys they like.
The couples, obviously, go out and do the things normal couple do.
For unattached guys, this is the day they find out which girl (or girls) is having a crush on them. The popular guys would get tons of boxes, while the not-so-popular ones would have to buy chocolates for themselves so they don't look like losers.
If the feeling is mutual, then a month later on the 14th March, the guys would buy white chocolates for the girls in return. They can start dating, and take the relationship on from then on if they want.
Things are different in SINGAPORE. Over here, 14th February is the day when stupid guys like us get suckered into buying OVERPRICED roses, OVERPRICED soft toys and OVERPRICED chocolates from some opportunistic money-minded vampires to give to the girls who'd just sit there acting like a rich TaiTai wanting to be pampered like a spoilt princess.
Why? Because we want to me her feel SPECIAL. Because we know that if she sees all her pretty girl friends getting all these fancy chocolates and cards and roses and teddy bears, while she gets nothing. You BET she's gonna wither away and melt in a green pool of jealousy.
