ASIA
Thanks to a concentrated marketing effort, Valentine's Day is celebrated in some Asian countries with Singaporeans, Chinese and South Koreans spending the most money on Valentine's gifts.[34]
In Japan, in 1960, Morinaga, which is one of the biggest Japanese Confectionery company, makes the present habit that only women give chocolates to men. In addition, presents except chocoletes, such as candys, flowers, or going to eat dinner are not common, unlike western countries. It has become an obligation for many women to give chocolates to all male co-workers. This is known as giri-choko (義理チョコ), from the words giri ("obligation") and choko, ("chocolate"). This contrasts with honmei-choko (本命チョコ); chocolate given to a loved one. Friends, especially girls, may exchange chocolate referred to as tomo-choko (友チョコ); from tomo meaning "friend". By a further marketing effort, a reciprocal day called White Day has emerged. On March 14, men are expected to return the favour to those who gave them chocolates on Valentine's Day.
In South Korea, women give chocolate to men on February 14, and men give non-chocolate candy to women on March 14. On April 14 (Black Day), those who did not receive anything on the 14th of Feb or March go to a Chinese restaurant to eat black noodles and "mourn" their single life. Koreans also celebrate Pepero Day on November 11, when young couples give each other Pepero cookies. The date '11/11' is intended to resemble the long shape of the cookie. The 14th of every month marks a love-related day in Korea, although most of them are obscure. From January to December: Candle Day, Valentine's Day, White Day, Black Day, Rose Day, Kiss Day, Silver Day, Green Day, Music Day, Wine Day, Movie Day, and Hug Day.

Well... in actual fact, Valentine's Day is not a day that you show your affection for your boyfriend/girlfriend. Rather you could show it to your family, your friends... and even those around you whom has brought you sunshine and brightened up your day.
