Submissive men

PROMO ALERT!!!
Seems submissive from the promotion art, guy sheds tears.
Tags include regression, teary ML, misunderstanding (I think) and also the ML tries (at least we thing, I'm not sure yet) to kill FL and FL dies before he can kill her (or goes back in time) and tries to avoid it. Also ML has a sad backstory, I'm not sure about FL thoughh. Reading as we speak :P
