"(Y/n)!" Archer shook your form by the shoulders. The markings on your arms were glowing red, as well as a mark on your neck. Archer recognized it as a bite and glared. He held you close, trying to wake you from whatever dream you were having. 

When you had left him in the kitchen, he too felt like he couldn't move for a while. He gritted his teeth, and clenched the wooden spoon in his hand, trying to regain control over his body. It was hard to breathe, and all he saw was red. Even the kitchen had changed, turning into an abandoned, destroyed room, which was barely recognizable. The spoon handle crushed in his hand as he summoned a sword. Slowly against his will, the sword was inching towards his neck. His eyes widened, and sweat dripped from his forehead as the tip of the blade poked his neck.

"Oh, that's a good look on you~" Said an unknown voice in amusement.

When Archer regained control of his body, he looked over his shoulder, spotting a boy crouching over the table. Or what seemed like a table. The boy's wide eyes and smile made Archer summon another sword and put up his guard. "So, you're the other servant she summoned I presume?"

He grinned. "Maybe."

Glaring, Archer stood up straight. "What are your intentions with her? I have a feeling you don't want a part of this war."

The boy hummed, summoning his weapon. Archer clenched his swords as the boy playfully swung it around his wrist. "I find her interesting. I don't mind being in this war. I get to kill for the sake of 'justice'." He chuckled darkly. "Or maybe..."

"Get to the point." Archer growled.

The boy stopped swinging his weapon, slowly turning his dead eyes towards him. "I just want to make sure you won't get in my way when I have my fun with her."

"What do you plan to do with her?" Archer asked again, power surging through him.

The boy grinned, licking his lips. He then made a slicing motion over his neck with his dagger. Archer readied himself, before lunging towards him. To Archer's surprise, his blades only went through the boy, slicing through the air. That was when the kitchen returned to normal.

The atmosphere was no longer thick with fear or blood. He began to breathe normally again. After Archer quickly looked around, and was sure the boy was no longer near, he quickly left to find you.

You were passed out on the ground in your room when Archer found you. Your arms had red markings similar to the boy from before, and you were hot to the touch.

When Archer went to shake you again, your hand shot up and grabbed his throat. Archer's eyes widened as your grip tightened around him, with strength that obviously wasn't yours. He grabbed your wrist, coughing. "(Y/n)-!"

Your eyes, which were a different color, opened to his. Archer glared, recognizing the eyes of the boy from before. A wide smirk spread across your lips, and you winked at him, before falling limp again. Archer coughed and looked back down at your arms.

The markings disappeared when you regained consciousness. "What-?"

"(Y/n)! Are you alright?" He sat you up as you rubbed your eyes and held your head. "What happened?"

You blinked, turning to Archer after looking around the room. "What? What happened?"

He scowled. "I'm asking you that. What happened while you were asleep?"

You made a face, trying to remember what happened, when you spotted the marks on his neck. You gasped. "Archer, your neck!" Archer scowled when you changed the subject. You gently grabbed his jaw to move his head to the side, to better look at his neck. "Who did this to you?"

He sighed, moving away from your other hand when you went to touch his cheek. "Never mind." He stood up, helping you in the process. You stared while he closed his eyes in thought. When he opened them, he stared with such intensity you shuddered. "You are to stay be my side, no matter what. Understand?"

You nodded. "Right." He stared as you looked away in embarrassment. The way he said it almost sounded romantic. You then remembered something. "Did you finish cooking?"

Archer blinked, until he heard the smoke alarm go off.
