Ever since joining the Voltron team, you felt a certain attraction to Keith. It wasn't like any other attraction you've experienced before. You wanted to protect him, to claim him ,and make sure he was yours and only yours. You knew Keith and you were destined to be together, you wouldn't accept it any other way. You and Keith had a friendship, as most would see it. However, you knew how he felt about you deep down, he must have the same feelings toward you as you do towards him.

As most days, you headed down to the training deck to train with Keith. It's how you became such good friends in the first place, it has become sort of a schedule you both shared. Upon arriving, you heard grunting from inside the training deck. Keith was probably going at the gladiator trainer as always. Or what if he was fighting with someone other than you? What if it was him and another girl he picked up on a planet? You had to be prepared to keep Keith yours and no one else's. Unsheathing your training blade, you swiftly marched into the training deck. Upon your arrival, you saw Keith sparing with the gladiator program. Thank goodness, you didn't know what you would've done if he was training with someone other than you. You just know things would've gotten ugly for them.
"Hey, (Y/N). You're here early." Keith greeted you as he was in mid-spar.

"I wanted to train with you as soon as I could!" You said excited. You were happy to train with Keith, it was some of the time you had that was simply just you and him. You got quite jealous when he even talked with the rest of the team. Or when he would help out or give advice to one of them. You wanted his attention, his love, you wanted him. As you smiled at him he didn't take notice of the gladiator simulator swiping it's staff at his feet. Keith fell with a hard thud. You stared in horror as he groaned slightly in a sitting position.
How could you let this happen? You were supposed to protect him. You were supposed to dedicate your life to him, and you failed. He sat there hurt, you had to respond in some way. Before he could stand up, you quickly sprung into action readying your blade for the fury you were about to unleash on the robot.
"How dare you hurt him." You spoke as you battled with the robot. Pure rage flooded you as you swung and chopped your blade onto the robot. "How dare you!" You screamed as you beat the gladiator repeatedly with your blade. Eventually the robot fell. You climbed on top of it and began to pound into it with your bare fists. That thing hurt your Keith, you had to make it pay.

"(Y/N)!" Keith's voice echoed from behind you. Immediately you halted your movement to listen to what he has to say, his opinion was very important to you and you wanted to make sure he was happy. "What are you doing? You didn't have to take it that far. I'm just glad that you didn't get hurt, that was dangerous!"
Hearing Keith's worries about your safety made you feel happy and safe. He cared about you. You sat there smiling and awaiting his next words. He talked about how you could've gotten hurt, you wondered if he knew you would do anything for him. You would throw yourself on a sword if it meant his safety and happiness. Keith was your main priority.

Later that day you were walking to the kitchen to make lunch. 'I wonder if Keith ate? If he didn't I should make him food in case.' Your thoughts halted at a voice you knew better than anyone's. Keith's. You stoped at the door to listen to what he was saying. He seemed to be talking to someone in a small voice, not wanting to be heard.
"She just jumped in front of me. She was slashing that thing like crazy, it scared me a little. She seemed like she only cared about my safety and not her own. I'm worried, she's not her usual self." Hopefully he was talking about you, you didn't want him to be concerned over someone else. A second voice rang out from the room.

"Maybe I'll talk to her, see what's the matter." It was Allura's voice. 'Why as he talking to Allura? Was I not enough company? Why would he need to go to anyone else with his problems?' Anger blazed inside of you. You officially snapped, going around the corner at a fast speed you unsheathed your blade from your side and came speedily at Allura. You didn't care what the consequences were. When she was gone, you would have Keith to yourself, with no objections or distractions. Getting rid of Allura was the solution. She was why you didn't have Keith. She was keeping you apart! You released a laugh as you happily sliced towards the princess, being the fast weasel she was, she scampered out of the way before your blade made contact.

"I'll get you! You're keeping us apart! How dare you keep me from him. Once you're gone he'll finally be mine!" You screamed as you hacked toward the princess.

"(Y/N)! You don't have to do this! Pleas stop!" Keith cried as he restrained you and threw your blade to the floor. "Why would you do this?"

"I just wanted you to be mine~!" You smiled lovingly at Keith as his eyes showed increasing levels of fear.

"Why (Y/N)? This isn't the girl I knew." Keith was almost crying as he looked in your twisted, perplexed eyes.
