South Korean wedding/engagement info (Seoul)

I live in the UK, my girlfriend is in Korea in uni.

Basically near the end of Protected content plan on proposing to her. The only problem is that I don't know the cultural differences between proposing in the Uk and South Korea.

Any information at all would be hugely helpful. Types of rings that typically sought after, where people propose, any formalities that I'd need to take part in with her family etc?

Also I'd like to know about wedding culture in South Korea. How does it differ from western weddings? what will I need to look out for? any information at all would be useful.
