Whilst I read your O.S, the song " Say Something" began x). Loved your story ! Kind of sad...Don't know. Even if they are angry with each other, the way their relationship end is very hurtful. Well for me at least. But I'm kind of sensitive xD

It's been such a long while in which I can actually feel the character's hatred intensely. My gawd the chemistry and intensity btw them is so strong and mind-fucking (in a good way I mean, since I feel like I got pulled into the story). I look forward to more! :D

Ah, define ANGST. I'm not a fan of sad story endings, so I'm still wishing this oneshot would turn into a series, or at least have another chapter as continuation. Besides that, although I sorta get a feel of the characters' motive, I think it would be helpful to clarify that just a little bit more, since clues were already given, but the idea isn't fully apparent. That'd just take an eensy bit of editing, or you could add another chapter to explain it and give it a happy ending. (That's me trying to make a subtle appeal, hahaha. I just hate sad endings, is all, meheh.)

Also, just to put it out there, regarding elevator sex (or "elevator hate sex" as you more specifically refer to it)... There's just a part of me that cringes when it comes to the plausibility of something like that happening in reality... though this I understand this is fiction, so that's just my personal view/preference. (I mean, it's too risky... Someone might catch them or there might be some hidden camera or something, haha.) Nonetheless, it was an effective plot device suitable for the length and ending of the story. *thumbs up*

Anyway, that's just my two cents. Good storywriting overall, especially the ending. (Ack, my heart! *pang of pain*)
Kudos!
