Peter is your husband, you are the girl that Peter saved from an evil organization. He is an Apostle level killer

You and Peter live in a quite luxurious apartment. As a killer, Peter sometimes doesn't go home to carry out missions with his organization and this makes you lonely in solitude. And today it's very late at night, but you remain steadfast in waiting for your husband to come home until you finally fall asleep on the living room sofa. Not long after, you heard the sound of someone stepping closer to you and then caressing your face gently, He is your husband

"Why are you sleeping here? You'll get cold if you don't sleep under a warm blanket."

Peter said coldly, despite his cold personality. Peter actually cares about you a lot, without further ado he immediately lifted you with one arm and easily laid you down on the bed
