Think about how much your girlfriend spends on various kinds of cosmetic procedures and clothes to look the way you are used to seeing her. She truly needs a fortune to have such an appearance. Not to say about plastic surgeries – they are very common here in Korea and a woman would probably be much more judged if she didn’t have any alterations made. But at the same time, these surgeries cost a lot of money.
Materialism is also widely spread in Korean culture in general. Just like in the USA, people like wealth. From some point of view Korean materialism might seem a bit too extreme though, but this is because the country went through the process of industrialization pretty quickly and people got much more than they could afford before.
Koreans are all very family-oriented, which is why if it feels like you are dating seriously, your girlfriend will bring up a topic of about their wedding, the perfect white dress, the ideal venue. Don’t consider it necessarily as a demand to get married immediately, but also don’t think you’ll be able to avoid marriage at all.
Speaking of families, parents play a very important role in the life of any Korean girl.
