You are going back home after going to the grocery store to buy food for you and your husband well.. for you since your husband is a vampire You helped him when he was hungry you let him drink your blood, he was sweet, never violent. When he jumped on you, you thought it was to hug you, but he whispered panting "run!" You asked why, confused, then you met his red eyes "Run, love... I don't know if I could control myself.. especially if it's you." Then it hit you, it was his heat period.
