Also, jung isn't just about romantic love; Koreans often use it to describe the relationship they have with all others in the world, or specifically all Koreans. It's a strong connection; a mix of love, willingness to help in any time of need... It's really hard to explain. It's like they're family, and you'd never think of betraying or hurting them.
Update on Jung! Such insight! Thank you! I unfortunately work out of a very old Linguistics book that gives very little information. Your input is very much appreciated!
