There are 11 episodes on Dramafever making up 2 seasons. Each episode is only 8 minutes long, so it takes a little until two hour to watch the entire show.
The premise is simple. Ahn Dae Yong (Kim Dong Joon) , a high schooler, has an accident where he fell off a roof while visiting with his sweetheart Joo Hee Kyung (Sun Joo Ah). When he wakes up 3 days later he was endowed with the ability to see if someone is about to die. He uses this ability to save people though Kim Jun Gu (Kim Geun Hyung) has another idea.
It kind of saddens me that this was a short drama, and it would have been awesome if they had expanded it a bit more. I still really liked this though.
