OK, so this is like the first piece of long fan fic I've finished in forever. I'm not 100% sure of it, so please tell me if it's shit or something. Anyway, my first Castle fic.

Title: That Jerk Castle
Fandom: Castle/HIMYM
Pairing: one-sided Barney/Robin
Rating: PG
Wordcount: 1270
Warning: mild language
Summary: Barney is irrationally mad at Rick Castle for talking to Robin, and Castle gets Barney completely wrong.

( He’s a charming womanizing jerk. You’re a charming womanizing jerk. You guys’d probably hit it off. )
