Store fronts have been advertising White Day for a few weeks now and I finally know what it means. In S. Korea, the 14th day of every month is a love-related day. February 14th is known as Red Day, March 14th is White Day, and April 14th is Black Noodle Day. These are the three most important of the love-related days.
From what I understand, it is the woman's responsibility to remember Red Day and give chocolate gifts to men. Then, on White Day it is the man's turn and they're expected to give non-chocolate candy to the woman (or women) who remembered them the previous month.
On Black Noodle Day, unmarried 20-somethings, who didn’t receive any gifts on Feb. or Mar. 14th, can join other singles at Chinese restaurants around the country to eat black bean-paste noodles (jjajangmyun짜장면). I think I've had these noodles and they're pretty good, but 3 months into the year do you really need to be reminded if no one thought of you on the previous love-related day? On the other hand, if you meet the love of your life on Black Noodle Day then it's probably worth it.
I found a website that lists the other love days as:
January - Candle Day
May - Rose Day
June - Kiss Day
July - Silver Day
August - Green Day
September - Music Day
October - Wine Day
November - Movie Day
December - Hug Day
