So I've been wanting to read it. But i have a question. Does this have a sad ending?

yes, hurt you deeply to the point of you can't turn back.

i started crying after the first chapter so....

Yes :(
The real angst story.
After read it, almost 1 month, I can't move on. Suddenly crying everytime remember the story (-----___-----)

No, this is a fluffy yaoi story full of smut... All cotton candies and unicorns..
