I watched it some time ago. I'm not sure it was a kdrama, movie or shortfilm.. but maybe someone has heard of it. There is a couple. She likes watching the stars and aurora (northern light) He likes paragliding because she likes the aurora and he wants to take her paragliding into it. (kinda spoiler alert) in the end he takes her with him and they glide away into the aurora. I know this is not very much information.. but maybe someone knows what i'm talking about. (maybe it's not even korean, but that's how i remember it)
