Captivated Ajin (Yandere!Kei NagaiXReader)

Between Real and Fake

Kei climbs his way down to reach you. You were having too much fun that you didn't know he stood by and watched you gleam like the sparkling water. He watched you frolic in the water full of happiness. He hasn't seen this side of you. From the moment he saw you, his blood began to boil. He recalled something that pissed him off when he passed through the village.He kept hearing people talk about you, the "newcomer", asking for Horiguchi. Mr. Horiguchi seemed pleased with you. Everyone started spreading rumors that you were somewhat flirting with Mr. Horiguchi because he kept talking about you. He made a remark saying that you were too good for Kei, and that you should just be with him instead, but that was the time when he was drunk. Kei felt irritated just hearing it from Mr. Horiguchi. He recently just spoke to him, calling him a virgin for having someone like you, and that he wouldn't stand a chance with you at all. His pride was hurt because of you. It was as if you insulted him for just standing around, calling yourself the supposed "girlfriend". It's true, you're not his girlfriend. But for that reason, Kei felt angry that you talked to Horiguchi today.

"This is so fun!" You played trust fall with the water, swimming around.

He understood the fact that it was a humid day today but what made him wonder was why and how you end up here. He waited for you to be done but it seemed like forever and the thought of getting out of the cool water never crossed your mind. 

"I'm free!!" You shouted.

Kei noticed that your feminine features were catching up to him. He noticed how small your waist was compared to wearing clothes. Your figure was what captured his vision. You were the only thing that stood out in the sparkling ocean. He focused on the scar that was made on your back as you played. It was like you were a fish dancing in the water. No wonder why Horiguchi had his eyes fixated on you. 

"I've had enough of this." Kei sighed and dropped his things and took off his shoes. You didn't notice that he was approaching you from behind. At this point, his pants were soaked up to his thighs. 

"You suck, Kei!!" You shouted into the horizon before you felt a something grab your wrist.

You swiftly turned around to meet Kei's red orbs, face to face.

"Oh shit!! W-What are you doing here, Kei!?" You nervously tried to pry his hand away as he held you tighter. You felt embarrassed, not because you were in your underwear but the fact that you shouted that out.

"It's time to go. C'mon." He drags you from behind as you stumbled. 

"H-Hey wait! I kind of want to stay here a little longer!" You told him.

He turns to you, staring at your curves and breasts before he met your eyes.

"Fine. Have fun finding your way back."

He sounded angry for a sec. You didn't know what was the problem with him. 

"H-Hey wait a sec! Are you upset at me?" You shouted, taking a couple steps behind him.

His back was turned to you. He didn't care to face you. With that, he pressed on to return to shore.

"Kei!" You called for him.

He ignored you as you shouted his name.

"Kei!!" You repeated.

"W-Wait up!" You tried to catch up to him as he went on first. You didn't want to get lost in the woods and You knew that Kei meant what he said.

Fortunately, he stopped when he reached the shore. You felt relieved that he stood there and waited. 

"Is there something wrong? Are you still mad about this morning? 'Cuz it should be me who's mad at you!" You jabbed him in the chest with your finger.

"Stop it." He slaps your hand away.

You knew that he meant something else. It wasn't about this morning. It was definitely something else.

"Then... W-What is it?" You asked.

He stayed silent, refusing to communicate with you.

"Kei, look at me in the eye and tell me. Is it because I'm giving you a hard time?" You rest your hands on your hips.

He looked away, staring into the water of the ocean. You sighed, giving in to defeat as you slipped on your dirty clothes and tied your hair up in a bun.

"Stop acting so childish." You told him before you left him. 

He remembered that those were the words he said to you after your first night here. You were right. This time, he was acting like a child, getting angry about stupid stuff that he shouldn't care about. He didn't have a good relationship with Mr. Horiguchi from the beginning. Even though he tried to make amends with him.

Your words fueled him. He felt angry when he shouldn't be. You're just his hostage. You shouldn't mean anything to him. Nonetheless, he followed you back into the woods, trying to reach you. As for you, you couldn't find the way back home.

"Which way was it---"

He finally caught up to you and grabbed your arm. 

"Hey, let go!--"

"Did you or did you not flirt with Mr. Horiguchi?" He demanded an answer, staring into your eyes, searching for them.

"What? Flirt? What the hell are you talking about?"

"Did you?" 

"Kei, please. If I had the ability to flirt, I'd get a boyfriend by now--"

He then held both of your arms in anger. He knew that he shouldn't get angry that you didn't see him as your boyfriend. He knew that this was all just pretend but it somewhat felt real for him. He was becoming jealous over a fake relationship that he made up between you and him.

"Just tell me the truth!" He slightly shook you.

You became confused and afraid like the time you first met him. You didn't feel safe since no one was around to help you. 

"Kei, w-what are you talking about?" You argued.

"Were you flirting with Mr. Horiguchi?" He ordered.

"No! Granny asked me to get carrot seeds from him because we didn't have any!" You explained.

He suddenly calmed down and raised a brow.

"What?" He asked.

"All I asked from him was a pack of carrot seeds! Where the hell did you get the crazy idea that I was flirting with him??" You pushed him away, trying to pat the dirt from your wet shirt.

"...... So you really weren't?" 

"No! Why are you so concerned about it?" You inquired.

"... It's nothing."

From there, he led you back home. The two of you did not talk on the way back since it felt awkward to do so. You didn't know what came over him or why it made him worry. You hoped that he would go back to normal or to the way how Granny views him.
