She's so perfect, Crona thought to himself as he watched (Y/N), who sat beside him, taking notes.
(Y/N) was Crona's best friend, and the only person who really brought him out of his shell. He loved being around her and talking to her... He loved her.
She was amazing; everything about her made Crona madly in love. Her smile, her voice, her eyes- everything. Crona wasn't sure of many things in his life, but he was completely positive that he was in love with (Y/N). That would never change, he knew. He would give or do anything for her... Anything.
Crona had been keeping his feelings a secret for quite a while now, and it was getting increasingly difficult for him. He had to tell her, he just had to. Besides, he knew that she would love him back... Why else would she be so kind to him? It was only fair that she returned his feelings, given how much he had risked, and would continue to risk, for her safety and happiness.
That's it, he decided, I'll tell her tonight.
As the bell rang, signaling that the school day was over, (Y/N) got up and rushed over to Death The Kid, seemingly forgetting about Crona. An intense spark of jealousy flared up in him as he saw her smiling and laughing because of Kid. She even appeared to be blushing.
No, she's mine, Kid. Mine! Crona's mind screamed.
He stood a little ways off from the two, waiting for (Y/N) to come and talk to him, but it didn't happen. She walked off with Kid, leaving Crona behind.
He stood in shock, watching the two as they disappeared from his sight, completely forgetting him. Crona almost cried, but he held it in. He still had a chance. He would confess to her before Kid could steal her away.

That night, Crona found himself outside of (Y/N)'s dorm room, feeling a little nervous. No, he felt extremely nervous, but he knew he had to do it. He couldn't wait any longer, or Kid would take her away from him, and he could not allow that.
He knocked, swallowing the lump in his throat. Within a few seconds, (Y/N) was standing in front of him, looking slightly confused, but still wearing her usual lovely smile.
"Oh, hi there Crona," she said softly, "I wasn't expecting you!"
Crona tried his best to hold back a blush, smiling back. "I-I'm sorry, (Y/N). I really need to tell you something, that's all..."
She giggled and opened the door wide enough for Crona to come inside. "Of course! You can stay, just have a seat, I need to go check something, I'll be right back!"
Crona nodded before heading into the next room. What he saw next caused him to freeze in his tracks. Sitting on one end of the couch was none other than Death the Kid.
"W-what are you doing here?" Crona whisper-yelled from where he stood in the doorway.
Kid turned his head, eyes widening a little, before returning to a calm and friendly smile. "Oh, hey there Crona! I didn't know that you would be joining us."
"What do you mean, 'us'?" Crona growled, "You're not supposed to be here!"
"Wha-" Kid was cut off by Crona flinging himself at him, pinning him down and grabbing him by the throat.
"What do you think you're doing?" Crona asked, his eyes consumed by madness and bitter hatred- not from a kishin, just pure psychopathy.
"C-Crona! What are you-" the shinigami boy was cut off once more by Crona tightening his grip on his throat.
"Why are you doing this to me, Kid?!" Deep, helpless sadness filled Crona's eyes, and tears began to form. "I thought that we were friends! Why are you trying to steal (Y/N) from me?!?"
Kid was filled with pure terror, he couldn't react.
"She's mine, Kid. Only mine. All mine," Crona continued. "Miiiine. Why don't you understand that? Why were you trying to interfere?!"
Kid couldn't have replied, even if he'd known what to say. Not only was the black-blooded boy cutting off his airways, but his long, bony fingers were putting a deadly amount of pressure of his throat.
"I'm going to kill you, Kiddo. Then she'll have to love me, and only me! You won't be here to take her away anymore!" Crona explained in a sing-song voice, a mad grin plastered onto his pale face.
"Crona, please don't do this," Kid choked out, "I-I'm s-sorry!" He was in tears now, and losing his conciousness.
"No, no, no Kid. That's not allowed. It's far too late for any apologies. You weren't being a very good friend, you tried to take the one thing that was important to me, and that was mean," Crona replied, frowning a little, "I do, however, know how to deal with people like you."
With that, Crona applied as much pressure as he could muster onto Kid's throat, his fingers breaking through the weak point and killing him. Blood immediately engulfed Crona's fingers, the blood of his former friend.
(Y/N) walked into the room, her breath hitching in her throat as she caught sight of the bloody mess in her living room. Crona hovered over Kid's dead body, staring at the blood on his hands with a look of satisfaction.
"Cr-Crona!" she wailed, stumbling against the doorframe.
The pink-haired boy jumped from his position over their dead friend, and he ran to his love, who was on the verge of tears.
"I'm so sorry, (Y/N)... Please don't cry," he pleaded, holding the girl to his chest, "I did it for us... He was trying to steal you from me... I just... I just wanted you to love me. Not him."
(Y/N) stared up at Crona, taken aback by his words. "Crona..."
"Please don't hate me! Then I'd have to kill you too, and I don't know how I would deal with not having you..." He whispered sadly.
"I-I..." (Y/N) choked on her words, clueless as to what to do.
"Y-you love me back, right? I really hope you do... I killed Kid for you, (Y/N)... I'd kill anyone for you..." Crona held her shoulders, looking her in the eyes.
She couldn't tell him no, she didn't want to die, especially not at the hands of who she had considered her best friend. Besides, not many people would love someone enough to kill for them.
"Y-yeah Crona... I love you too. Thank you, for everything." (Y/N) replied, hugging the bloody boy once more.
Crona smiled proudly, glancing over at the dead body of Kid.
I'm sorry I had to kill you, friend, he said silently, but I could never let you have my (Y/N).
