Miss  Jekyll and Miss Hyde

"So you let him perform cruel experiments on you?" Beruma asked, a note book and pen in hand.

"No..." You trailed off.

"Pardon me?" She asked.

"No his experiments are not cruel. But yes, I can confirm that I let him use me as his subject." You nodded at her, as she wrote those down on her trusty orange notepad. "I let him, because... I love him..."

"Wait, you, L/N Y/N, let Kusha Kaga to be his test subject because you love him? Jinkies, why?" She exclaimed.

You shrugged. "There's nothing I won't do for him." You weakly smiled, imagining the time when he kissed you by the lips, to transfer the serum in your mouth for you to consume.

"So what was the experiment he gave you?" Beruma asked.

"He made me drink a serum he called 'JH7', or 'Jekyll and Hyde serum'. So far, he thought that it failed. But I haven't told him that the side effects given are slowly occuring everyday." You said.

"And what are the side effects? What was his intention?" Beruma curiously asked.

You but your lips at the second question. "The side effects are severe migraines, breathing difficulties, and having an extreme urge to vomit... His intentions... His intentions... He never told me anything about it. To be frank, I never thought about it until now." You said.

"Kaga... I am not sure about this..." You trailed off, looking on your shoes as he readied a the test tube rack filled with unrecognisable fluids.

"Why not, darling?" He asked, putting all the fluids in a beaker, before dropping a small drop from the medicine dropper.

"I... Just don't... I-"

"You don't trust me?" Your eyes widened in shock.

"K-kaga, no... I am just unsure about this. That's all." You said, staring at your shoe.

Unknown to you, he put some of the liquid in his mouth, then walked towards you. He gave grabbed you by the chin, with his thumb and index finger. He gave a smirks as he watched your vulnerable state, as he leaned closer. You backed away, until you felt the wall on your back, mouth slightly opened in shock. He took this opportunity to push the liquid in your mouth, and made you swallow it.

He put his tongue in your mouth, exploring your mouth, as you did the same with him. You caressed his cheek, feeling some of the liquid drip on the side of your mouth. When the two of you pulled away, a thin string of red colored saliva connected the both of you.

He wipe the liquid that dripped from the side of his mouth with his sleeve, before smirking at you.

"I look forward to seeing you here everyday, my love~"

"What does the serum tastes like? How did it feel when you consumed it?" She asked.

"It tasted like water at first, then turns bitter. My throat slightly burned when I swallowed it. And it felt warm in my body and spread all over. Then it gives off a feeling of euphoria... Then there came nausea and lightheadedness." You stated.

"Okay... How many experiments did he performed on you...?" Beruma asked.

"Two. He made me drink the serum at first. Then, when he said that 'it didn't worked', he injected me with it." You said. "I can say that it's working... These symptoms are the given symptoms he said that I may experience."

"Alright. What do you think does the serum do?" Beruma asked. "Considering he named it Jekyll and Hyde Serum... It may have something to do with separating a persona or something. You know, Jekyll and Hyde in general." She shrugged.

"I... Don't know..." You said, unsure of what to say.

"Since the first experiment did not worked," he tapped the fragile syringe containing a red liquid within it, making a light clinking noise as he does so.

You gulped upon seeing the needle. "Umm, Kaga... I-"

"Is there something wrong, darling?" He menacingly smiled, his eye piece shining as he does so.

"N-nothing..." You looked down.

"No worries, darling," he kissed your cheek. "It won't hurt... Much." He tied a piece of cloth on your arm, cleaning your skin with a damp cloth, before holding a cotton by your arm, next to the needle. You bit your lips, as the cold needle touched you. He notices this, then leaned closer to you and pressed his lips to yours. You kissed back, feeling nothing but his presence.

Unknown to you, he had slowly injected the liquid in you as he kissed you. When he pulled away, he smirked at you. He then tapes a bandage on your arm.

"I'll see you tomorrow, darling~" he gave you a quick peck in the lips, before turning to leave you.

"AAAAAAAGHHHH!" Screaming in agony, clutching your head to ease the intense pain. Your breathe drew shorter and chest tightened. "Gaaah, GGAAAAAAAAAAAAAHH!" You screamed, clutching your chest.

Soon enough, you were greeted by silence. To silent for your liking. You slowly looked up the mirror with a smirk. You were paler than usual. Your eyes were glowing a neon blue hue that wasn't your eye colour. Your hair had a neon blue Streak, that glowed. Soon, the neon glow faded from your eyes and hair as it slowly turned normal.

"Free..." You, no, the one who took over your body, said in a low, raspy tone.

"Kaga... Do you love me?" You weakly, drawing invisible circles on his chest as you lay your head by the crook of his neck.

"Of course, my love." He kissed your forehead. "I didn't gave you my virginity for nothing, Y/N." He chuckled at you.

"So you won't just use me for your experiments?" You glanced up to him, with a genuine smile.

"Of course not, my love... I love you, Y/N..." He said, taking a quick peck on your lips. You entwined your fingers with him with a smile.

"I love you, too. You're the best thing in my life. Megami and Kencho are jerks, father favoured them both. You're the best, Kaga. I swear my loyalties to you forever... I really love you to death..." You said, dozing off with the presence of Kaga. He bit his bottom lip in guilt. Everything he said about you... We're all false. And he feels guilty about it.
