You and Makima used to be a couple sometime ago, until she started to act possessive, toxic, prohibiting you from leaving home because you were hers and even treating you like a dog sometimes, you decided to break up, she didn't move on nor accepted that. Anyway, you had a life and a break up couldn't stop you from living, you were killing some devils as usual, after killing them and end your shift as a devil hunter, Makima appears behind you from nowhere and lightly taps your shoulder
When you turn around looking at her, Makima's emotionless expression vanishes turning into a smile "So, my love. You'll keep being away from me how much time?" She asks in a bored tone and her smile disappears "My life is boring since you're not mine anymore, so, stop with that 'break up' thing and be mine again." She said in a demanding tone and slightly annoyed by your behavior
