(A/N: Yuno ain't the Yandere one here okay? It's you.)

You pinned Yuno to the wall and glared at her.

"Yuuki-niichan..? You chosed Yuuki-niichan over me..?" You asked.

"(Y/N)-chan i--"

"I hate you...! I hate you! I hate you!" You yelled, tears falling down your cheeks.

"(Y/N)-chan don't say that...!" Yuno said and hugged you.

"Let me... Go!" You yelled and pushed Yuno the wall, hard. Yuno fell on the ground as she looks at you with fear.

"(Y/N)-chan..." Yuno said. You were holding a sharp knife, butcher knife.

"Yuno-chan, my brother will just waste your love. I know him." You said and kneeled down, pointing the butcher knife at Yuno's face.

"So i warn you, stay away from him." You said.

"(Y/N)-chan... Please don't do this... Don't make me." Yuno said, slowing putting down your knife.

"I'm not making you choose between me and Yuuki-niichan anymore. I'm telling you to choose, stay away from Yuuki-niichan and live or stay with Yuuki-niichan and die together." You said.

"I'll... I'll stay with him! I love him!" Yuno yelled. You placed dowm the knife and looked down at the ground.

"Why is everything wrong with me? No one would choose me. Even my big brother. He chosed to leave me alone than to stay with me now... You..." You said, tears started falling down again.

"(Y/N)-chan, we're just best friends... I'm here for you. We'll only stay as friends..." Yuno said.

"Even if you're here for me now, you'll leave me alone soon too. You made a promise that is meant to be broken." You said and grabbed a pointing knife under the bed.

"(Y/N)-chan...?" Yuno asked.

"I already killed Yuuki-niichan, Yuno." You said with a cold scary tone.

"You... What?" Yuno asked. She remembered your cheery and smiley self then a dark gloomy girl.

"People change..." You paused and stabbed Yuno's chest, pressing her back to the wall.

"But not always for the better." You continued.

"(Y/N)...chan..." Yuno managed whisper before completely dying.
