Overhaul narrowed his eyes as he watched Y/N greet his assistant with open arms. The male wearing a white raincoat took off his mask, and smiled at them, leaning forward to hug Y/N.

"Ah, your hair is so soft!"

Y/N commented as they brushed a hand against Chrono's white arrow-shaped locks, and the white-haired male chuckled, rubbing the back of his neck sheepishly.

"Yeah, I used a special sort of shampoo... It's really good, wanna know the brand?"

"Wow, really? I'd love to-"

Overhaul was tired of watching this go on. He walked forward briskly, and grabbed Y/N's wrist, making them yelp in surprise. They looked up at him with round eyes, and his heart clenched painfully. 

Y/N's mine.

He dragged them to his room, ignoring Chrono's apologies. When they finally made it to the room, he slammed the door behind them. He breathed heavily as he stared down at Y/N, who had a confused expression on their face. Overhaul pulled down his black face mask.

"K-Kai...? Are you alrigh-"

Overhaul stopped them from finishing their sentence by rushing forward to smash his lips against theirs, making them whimper. They tangled their hands in his hair and tugged hard on the strands, making him flinch a little. However, he didn't let the pain stop him, and he just kept Y/N pinned up against the wall.

Overhaul let his gloved hands run all over Y/N's body, and broke away from Y/N to bury his face in their neck. He breathed in their soft scent, and started to nip at Y/N's skin with sharp teeth. They squeaked in pain, and he smirked against the flesh. 

"Wh-Why are you doing this, Kai?"

Y/N said quietly as they let Overhaul do his work on their neck. When he was finally satisfied with the end product, he pulled away, rubbing his mouth with the back of his hand. He pulled the mask back up.

"I was jealous of you and Chrono. You're mine, and you shouldn't be touching him. I'm the only one you should ever touch."

Overhaul said, cupping Y/N's cheek with a hand. Their eyes widened in realization, and they looked down in embarrassment. 

"I'm sorry, Kai..."

He was silent before whispering through his mask in Y/N's ear,

"Maybe I need to punish you so that you remember you're mine."

Chrono was startled to hear the sound of Y/N squeaking in surprise, quickly followed by the deep chuckle of Overhaul. There was a loud thud against Overhaul's door, and Chrono knew it was time to leave.
