Yandere!Seven x MC

"MC, why are you so perfect?"

Seven smiles at the photo on his wall, that pictures a brown haired girl smiling sweetly at the camera. Seven, enchanted by the girl's honey eyes and her full lips, can't stop himself as he traces the girl's jawline with his nail, hoping he could do that in real life instead that with a picture. He then dramatically sighs as he says:

"One day, you'll be mine, sweetie."

He then continues to stare at the picture, touching MC's face continuously.

"And once that happens, I will never ever let you go away from my sight."

Seven moans and grunts as he keeps moving his hand over his penis, licking his lower lip as he looks at the cameras he had installed in his loved MC's. He masturbates each and every night, checking you out as you undress and change clothing. Sometimes he is even able to see you totally undressed, that turns him on so much. This was one of those opportunities. Seven moans harder at the sight of you getting naked, the girl's body making him blush; the dim light making the atmosphere a lot sexier.

"Mmmm… MC… H-How much I would pay to fuck you…" he says, his dick slick with precome.

One more thrust in his hand and he comes, moaning out the girl's name as she puts on her panties.

Zen kisses MC, as Seven secretly watches them. They kiss passionately in a dead end road, their tongues tangling. Seven grabs his glasses and holds them as his hands tremble with anger. Blood boils through him and the aner he has inside is eating him out. He hides again as MC leaves Zen alone. How can such a perfect being like MC prefer such a narcissistic asshole like Zen? He decides himself on what to do, as he raises the axe in his hands.

"I'm so sorry, Zen, but you deserve it, since you are separating MC and me."

"What the hell are you doing, Luciel!?"

He turns around, recognizing Zen's voice.

Angrily, Seven swings the axe and cuts Zen's head out. He doesn't even regret this act, and actually enjoys seeing the blood running down from Zen's neck.

MC cries on Seven's shoulder, feeling devastated as the news that Zen is dead had come to her. Seven faked sadness and compassion for the girl. She is devastated since all she wanted, the man that had loved her so much, was gone. Seven doesn't like seeing her cry so he wipes her tears out of her eyes.

"I am so sorry for you, MC… Please, stop crying."

"But… Who can be so cruel to kill someone like him?"

Seven felt mixed emotions, half of him felt rage, hearing MC praise Zen, since all he wanted was her to praise him, his love for her was truly sick, but also happiness, since there was no one in between their love. Seven hugged MC and whispered into her ear:

"No matter what happens, I will always be WITH you…"
