A few thoughts.
Demon King: Okay, you are bi dude who wants that cute boy hero, so what of those girls?
Mars: Honestly? They are all the most toxic, rancid bunch of all time. Cecilia is honestly the worst. She could just leave my Eren alone, but she has this insane obsession with my Eren.
Demon King: Huh...so you don't like her as much huh?
*Wonders about Cecilia's face if somehow she found Eren dead.*
