Wow

Chapter 1: Well this was certainly an unexpected bit of tortured activity to be suddenly dropped into. The intro gives a slight hint/warning of what's to come but you chose an interesting spot to introduce us in regards to Kibum and his deal. And all I can do is feel sorry for his brother. >.> With him being an empath, that would likely be a particularly frightening experience indeed.

Though I was a little confused about Kibum's having 'given enough for three people to be reborn' though I'm presuming you were referring to years. And in that regard, I think you managed a nice play on words in indicating that he hadn't only given up that time, but by the end of your short, we understand what else he lost. Goodness, what a situation to be in too. Especially because he's completely aware but utterly unable to do anything.

I'm personally skeptical that a cleansing would have done much to change his fate but it was a nice thought, if a bit late to be of any use. You do a really good job of conveying Hyungjun's panic though and it comes through well in the writing. So good job overall. Even with it being as short as it is, you might consider breaking the second chapter up into even smaller paragraphs to chunk the panicked sections around the possessed contortions and so on. Just a thought. ^_^ Thank you for sharing!

Chapter 1: Gawsh...this is so.....creepy....i wonder what will happen to Hyungjun now...or maybe it's obvious what will happen to him?...aahh, it's driving me crazy thinking...i wonder what's the story of Kibum's deal with the Devil too...is this really the end? no prequel/sequel?...it's a really nice suspenseful short story though...personally i find it hard to describe scene that will evoke fear and suspense from readers, but i think you did really well. Thanks for sharing the story.
