Read their card, its really in-depth!
The story involves a man who tried to jump off a bridge but actually just got stranded on an island in the middle of Seoul and can't get off AND a girl who doesn't leave her room ever.
They end up communicating and the story is really cute.
There actually is very little dialogue, so I watched it without subtitles to test my Korean!
I watched it on PutLocker but I heard that its also on Netflix maybe?
