South Korean couples often expect each other to follow romantic customs, a source of big business here. In addition to Valentine's Day when women give chocolate to men, there is White Day on March 14 when men give sweets to women. It is easy to guess what to give on Rose Day and what to do on Kiss Day. Some businesses exclusively serve couples by selling identical looking T-shirts and other apparel that can be paired. Some offer special discounts for couples. The list goes on.
Korean couples celebrate not only a one-year anniversary, but also 100 days since meeting. Between keeps a count, serving as a reminder for people like Ham, who marks such occasions by writing a poem, giving a gift or dining at a fancy restaurant. Ham and his girlfriend have been together for more than 1,000 days.
