?Nagisa Shiota x Reader? [slow updates]

||morning||
You sleepily walked to school, rubbing your eyes every so often. As you walked you suddenly heard a pair of footsteps coming your way.

You spun around with a bright smile to see Nagisa walking and talking to Kayano-chan.

Your heart beat froze and broke in your chest.

'Wh-What's this feeling? My chest hurts whenever I see Nagisa with Kayano. . . But why?' You thought as they both waved at you.

You forced a smile onto your face and raced over to them.

"Hey guys!" You chirped happily as you held your book bag behind your back in a cute manner.

"Hi!"

"Hey!"

"So do you wanna help me attempt to assassinate Koro-Sensei?" You asked with a smile.

Nagisa stared at you for awhile, while Kayano pressed a finger to her chin and thought for a few seconds.

"Meh, assassinating isn't really my thing sooo~ I'll have to pass," she replied with a small sigh.

"Yeah me neither, I need to focus more on my grades," Nagisa answered as he closed his eyes calmly.

"O-Oh Okay!" You tried to chirp happily. You tried hard not to yell or cry, but it grew really hard.

You felt as if you were about to explode when an arm was wrapped around your shoulder. Your face was pressed against a chest which made your eyes widen.

"Don't worry (Y/N) I'll assassinate him with you," cooed a sadistic voice.

"Karma?" You asked as you removed your face from his chest.

"Yep, the devil himself," Karma stated as he winked and stuck his tongue out.

"Whatever you say," you laughed as you ruffled his hair roughly.

Nagisa scratched the back of his head and looked away from you.

"Well sorry guys but me and Kayano have to get to class early to start on a project soo~ bye," Nagisa stated quickly as he grabbed Kayano's wrist and raced towards the school.

"Wait but I don't remember having a project assigned!" You yelled after them.

Karma removed his arm from around you and shoved his hands into his pockets.

"Hmm~ it seems that Nagisa is getting jealous," he murmured as he turned to you.

You raised and eyebrow a little confused.

"Jealous of what?" You asked as you walked alongside Karma.

"Well how strong our friendship is," he mumbled as he closed his eyes.

"E-Ehh?! But why?" You exclaimed as you held your book bag in front of you.

"I have no idea. . . But it may be the same reason whenever you see Kayano with Nagisa your heart hurts," Karma explained with a small smirk.

"What the?! How did you even know that?" You asked loudly.

Karma chuckled as you both approached the classroom.

"I could tell by the look on your face when Nagisa declined your assassination invitation," he stated with a smile.

"O-Oh," you murmured as you approached the school gate.

Karma stopped walking all of a sudden and turned to you.

"Hey, whenever you see Nagisa with Kayano, don't get jealous or mad. Just hang out with them so you can form a stronger relationship with Nagisa and Kayano," he explained as he ruffled your hair.
