I even bought the cakes to give to the other people in my building. Before a wedding the groom and his friends will party down the street carrying bridal gifts in a tradition called haam . When they arrive at the brides house they will raucously insist on compensation for their hard partying. In modern Korea this is when something like a set of rings, watches and other high end items will change hands. Traditionally the gift was principally food and clothing.
Korean culture extends into every aspect of life.
Koreans generally eat nothing but Korean food, though they may go out for pizza or fried chicken. Korea is a country where people get married in wedding halls that turn out new brides and grooms like bakeries turn out loaves of bread. See one and you've seen them all. However, when close friends like Chayyung get married, I do attend. In the second photo Chayyung suffers through yet another adjustment to her veil by the wedding hall employee who seems to have no special job besides adjusting the veil and the train of the dress.
