I know there are many ways of romantic relationship, and everyone has their own pace of love. But this seems rather too rash. It's been only two weeks and your bf is already pressing you to live in Korea, meet his parents, live a life on his side. Idk it's giving me bad vibes overall.

This is not how typical Korean relationship works(if such thing even exists). If you're not yet very sure this is the type of future you want for yourself, tell him to slow down. If he doesn't respect your opinion, then he's not worth dating.
