Hanzo Shimada wasn't used to this newfound feeling in the pit of his stomach, an unfamiliar churning making it hard to focus on the issues at hand. Through the war that was tearing everything near and far apart, to the spats that were causing irreversible damage, the last thing he needs is more drama. But when wannabe-cowboy Jesse McCree walks into his life, his life is turned upside down and all of a sudden he is not the calm man he once was.
With a cowboy dominating his thoughts, and the feelings only getting stronger what will happen to the emotionless man. Will he give in and act on impulse, or will he let this fleeting love get away from him for fear of making things worse for himself.
(AU where Hanzo doesn't feel anything because it was beaten into him as a child that he couldn't feel things. TW's include child abuse, though there's only one major mention in chapter one.)
