"Red Means I Love You."

Jesse Cassidy (I prefer this name for Cassidy.) was a part of Blackwatch when he was very young as a man who had to choose between jail and a group that gave him a living chance. While on a mission, Cassidy and the gang are on a rescue mission that quickly turns sour when their target, Y/N, has a little too much security around. It makes it impossible to get him.. yet years later Jesse thinks he sees the same guy he's left behind. A curtain obsession bubbles in his guts and head and things start to get serious.
