This idea came to me as I was writing the final chapter of my previous fic. However, if you came here from 141224, I think I'm going to disappoint you. And really badly. I'm going to start writing from 2019, what you want to make of that is purely your prerogative. To be honest, I don't think this is the easiest thing to write. In fact, I think it's going to be pretty difficult. I don't know how long it's going to be. 

I'll be assuming that the level of medical technology is identical to what it is today. My premise is indeed a huge coincidence, especially in Korea. I am uncertain that this is 100% medically accurate, though I can tell you that it won't be way out either. Honestly, I don't know how the healthcare situation is like in Korea, so don't take my word for it. 

Finally, of course, I wish no harm to anyone whatsoever. It's just that I wanted to write a fic like that.
