Looking for a certain doujin

I'm looking for a doujin where it begins in the bar, with the man talking about how his girlfriend broke up with him, and then it goes to him having sex with a childhood friend, but it ends with it all just being a fantasy of his, and his friends saying how messed up it was and how they can see why she broke up with him.

I know, not a great description, but if someone could tell me the name of the doujin... Assuming I described it well enough.

Even So, I love you by Kosuke Haruhito

Thank you.
