The number of 'National Days' in Korea for this, that and the other never ceases to amuse me. They seem to start with Valentine's Day, a 'holiday' we're all used to. Although here, it's a day for the boys unlike at home where it's predominately a day for the girls.
Next, comes 'White Day' which is the same as Valentine's Day only it's one month later and it's a day for the boys to be spoilt by their other halves. Same date, another month on, is 'Black Day' which is, from what I can gather, a bit of a depressing day for singletons when they are supposed to eat black noodles to highlight their single status!
