RUMI β 3 feet long purple hair, brown eyes and always wears long sleeves to cover demon patterns. JINU β Black hair, brown eyes, varies tight and loose clothes.
The two were dating and Jinu finally managed to coax out Rumi to finally show her demon patterns instead of hiding them after they spread all over her body until her forehead. Legs, arms and torso were covered in those patterns, just like Jinu because he also was a demon.
Jinu had this demon cat/tiger, a big blue one who was completely cuddly and big like half of Rumi's body big but Rumi did not care, she loved this tiger. According to Jinu, his name was Derpy so that's what they called him everyday and always gave Rumi and Jinu cuddles when they were together.
One day, Jinu came home in a bad mood and stumbled into the kitchen where Rumi was cooking. He said, without any real cruelty.
J: "B!tch, what's for dinner?"
Rumi, sensing Jinu's upset mood, muttered. "Grilled cheese..."
Derpy was next to Rumi's side, snuggling into her contently and sometimes licked her demon patterns that were on her belly.
Jinu saw Rumi reacted and realized she wouldn't talk back to him, just accepting being called a rude name. He approached her and held her shoulder gently.
J: "If you ever let me talk to you like that, you better smack the demon out of me, okay? I don't want you to think its okay for me to talk to you like that, got it?"
He didn't want her to believe it was okay for him to call her names and accept it.
