It was lunch break when Lisa went on looking for Felix. She still knew his schedule, so she got real quick to the point that he must be in the third floor already for his math classes. Usually he spent his breaks in some corner by himself which she would take advantage of now.

Indeed, the boy stood far away from the others in some corner and read in his book. Right next to a store room with his back turned towards Lisa, "Perfect", she whispered to herself as she quietly approached her ex-boyfriend. As soon as she arrived behind his back, she grabbed him, pressed her hand on his mouth and pulled him right into the store room. She quickly locked the door as she had him inside, grabbed the knife she had in her bag as always and smiled at him. "Yo, long time no see, huh?", she said with an innocent smile on her lips.
Felix however was kinda shocked and stared at Lisa with widened eyes, he had literally no clue what was going on right now. "Since when do you carry around a knife-", he asked confused but unimpressed. He still was convinced of the fact that he was the most dangerous person in this town; little did he know that the calmest people often carry the deepest desires. "I carry around a knife since it's necessary to protect myself especially when I'm friends with killers", she said and grabbed Felix by his collar before she pressed him against the wall and lifted her knee right between his legs. Felix quickly shut his eyes and gulped because he was hella scared of a kick in his guts. But Lisa stopped before reaching his middle and only smiled at him, "I want to know the whole story of what shit you and Jungkook are pulling", she demanded and started to slit his throat a little bit. Not too much, only to cause a little bleeding. Felix bit his lips in pain but kept a straight face. "We're not doing anything", he only said but all he received was a hard kick between his legs which made him groan in pain. "Shut up", Lisa mumbled and slapped his cheek which really made him shut up.
"What happened to you?", Felix asked with his expression fading into a sad one, "You're not the girl I used to fall in love with."
Lisa inhaled deeply before she pressed the knife even harder against his skin. "You never were in love with me, stop lying asshole. You loved Jungkook all along", she said and her eyes got all teary. "The sad thing is that I believed you. I really thought you were different like the rest, I thought you liked me for me. But in the end I was just a way to get closer to your crush", she said and turned her face away for some seconds to fight her tears.

It would be a lie if she said she wasn't in love with this boy in front of her anymore.

"Jungkook and I were close all along", he started slowly as he saw how Lisa's strength facade was breaking from inside. "Remember how it all started when Jungkook got into your group? We wanted to play some games because he hated all of you guys, you were what we always wanted to be and it pissed us off. Yeah, but then Jungkook's dad got killed but that wasn't us Lisa! We had nothing to do with that. Jungkook got scared and wanted to stop the game, he thought if we keep doing this it'll get worse. But I wanted to keep playing so I said I'll take all responsibility for what happens, and he said I can do whatever I want if I found out who murdered his father and as long as Taehyung doesn't get hurt because at this point he was in love with him. I got jealous over it and tried to make him jealous too with being your boyfriend but he didn't care. All Jungkook cares about is Taehyung. Not you, not Jennie, not Jimin, not me. It's all about Tae.
So I started threatening him too but I swore to him it wasn't me. Of course he didn't believe me and thought it was me. I always threatened Taehyung with hurting Jungkook which worked amazingly. Those two are the perfect example of true love", Felix sighed quietly.

"But it all got out of hand when Jimin killed himself. That wasn't me, that wasn't Jungkook. That was Jimin himself, he left Jungkook a letter in which he explained it all. That day I made Jungkook kill Yoongi and Tae realised that Jungkook is cold-hearted and doesn't care. And that's when Taehyung understood most of it all", Felix bit his lips. "That's basically it, in the beginning we only wanted to scare you guys, we never wanted this to turn into a psycho murder game", he gulped as he saw how Lisa's expression got cold as ice.

"You forgot to explain the death of my Mom."
"Well, she treated me like a piece of shit so I got mad", he sighed. "It was easy to kill her. I have keys for your house, just like I have for Jungkook's. That's how I slit his wrists that night he slept next to Taehyung. I just let someone made me a copied version of the keys, yeah that's how I got into the house to kill your mother"

Lisa shook her head in disappointment, "And I really saw the best in you for the whole time", she whispered. "But there's nothing good inside of you. Not at all", she said and put her hands at the sides of his head. "Too bad, you're so pretty", she sighed.

"But your game is over", she said as she broke his neck with one single movement and watched him break down dead.
