There is also a night scene where Koreans go to special nightclubs called ‘na-i-te’ (나이트.) Korean guys go in with their friends and get a table. Korean waiters take the women to a certain table and then the two newly-met social groups interact.
In any case most of Korea’s dating culture involves introductions.
As a rule, a traditional Korean woman carried a small silver knife.
It’s interesting to watch American films emphasizing the 3-date-rule, because really? Of course, this is generalization and there are variations, but the main point is that although the ideology of sex is changing rapidly, mostly due to media, there’s still a stigma on girls having sex before marriage. The “proper” women must remain chaste, and the requirements of being chaste are utterly crazy.
As I briefly scanned over in my previous post “What to Expect when Dating a Korean Guy,” it’s normal for Korean couples to get couple rings as early as 3 months into the relationship.
