First songfic! I listened to the song on loop for ages (while drawing chibi ndrv3 girls XD).
*EDIT*
Holy shit. I just came from Lenku_Alli's apology video on YouTube about her edit of 'in a heartbeat' and what the fuck. People are sending her death threats and telling her to go and die all because of one video. What the fuck? I almost cried listening to her apology. She just fucking apologised to the people who are giving her fucking death threats. They should be apologising to her because telling someone to go and end their own life is probably the worst thing you could ever say. I'm disgusted with these people personally. I'm sorry for ranting. The oneshot will come now...

(Y/N)'s POV
~flashback~
Take your clothes and rip 'em, rip 'em off.

I called my boyfriend Kokichi Ouma after my best friend, Rantaro Amami called me over to the cafè to tell me that he was cheating on me with another girl.

Call these hoes and tip 'em, tip 'em off.

"You can tell tell them, you are mine! I'm sick of- sick of games, Kokichi!" I yelled into the phone at him. Rantaro was sitting across the room from me, texting Tenko, Shuichi, Kaede, Kaito and Maki to come over right away because I would need people around me during that time.

No more time, you lit the, lit the flame.

"(Y/N)! I'm sorry! I'm sorry! I didn't mean to! I love you!" He cried frantically.

We live in an age, where everything is staged.

Hot tears began to pour down my face and fall into my lap. The others burst into the room within five minutes of receiving the message from Rantaro. They all opened their mouths to ask if I was okay but realised that I was still on the phone and also sobbing, so I was quite clearly not okay.

Where all we do fake our feelings, I've been scared to put myself so out there.

"Time is running out, yeah?! Kokichi! Answer me! Why did you cheat on me?! I loved you!" I screamed, full of despair.

Need to let you know.
~flashback end~
~3 weeks later~

That last night I woke the fuck up.

I gasped loudly as my phone buzzed in the middle of the night. It was just junk mail, but I couldn't sleep so it couldn't hurt to just flick through Instagram and Snapchat, right?

I tapped on the yellow Snapchat icon and swiped though some stories.

"Hm. Let's see what shit he's put on his. Probably flaunting off his two whores..." I muttered to myself, tapping on Kokichi's story, his name and a Purple Heart emoji next to it at the top.

I realised I need you here, as desperate as that sounds.

He had posted pictures of us together, having fun... being happy...

Last night I woke the fuck up,

I realised I need you here, as desperate as that sounds, yeah, yeah.

"No... no... I can't. I can't go back to him no. Thanks, fucking junk mail. Waking me the fuck up." I mumbled quietly, slightly shaken. (XD I did it on purpose)

~flashback

Take these walls and rip 'em, rip 'em down.

I sobbed into the phone, Kaede and Rantaro patting my back, Tenko sitting in front of me, her hand on my leg.

Take my (uh) and sip 'em, sip 'em now.

"I will tell them I am yours and very, very proud." He said quietly.

"Don't bother, asshole. You cheated on me... I wasn't good enough for you...You had to find someone else... Sorry that I wasn't good enough..." I hung up and cried even harder.

I am forced to give in, give in now.

~flashback end~

We live in an age where everything is staged where all we do is fake our feelings.
"I... I should go to sleep..." I mumbled before lying back onto my (F/C) bed and drifting into unconsciousness.

In the morning
I had the strangest dream that night. It was about the time I went to the beach with Kokichi.

~Flashback~
"Kokichiiiiii! I'm dressed!" I called over to the purple haired boy. I was dressed in a (F/C) bikini, the bottoms having ruffles around it, creating a skirt.
"Wooowww, (Y/N)-Chan! You look so beautiful!" He said in awe.

I've been scared to put myself so out there

~later~
"WAAAAAAAAHHHHHHNNNN!! I dropped my ice cream!!" The small boy cried (rip Ouma's ice cream).
"Hey we can share this one if you want." I sighed.
"Are you sure, (Y/N)-Chan?" He asked.  I nodded in response and we began eating the ice cream together, a light blush on both of our cheeks.

Time is running out, yeah.

~flashback end~
I cried silently in a ball on my bed. I missed him so so much. I wanted the feel of his small, childlike frame in my arms again. The feel of his soft purple hair tickling my face. The sound of his signature laugh.

Need to let you know

I grabbed my phone and called him.
One ring...
Two rings...
"(Y-Y/N)-Ch-Ch-Chan?" He stuttered. He sounded so broken and like he'd been crying for days on end.

Last night I woke the fuck up

"I realised I need you here as desperate as that sounds!" I cried, all of my despair flowing out of me in waves. I told him about the dream I had that night.

"I'll be over in 5 minutes, okay?" He said and hung up. I quickly shoved on a pair of black jeans, a white shirt and a (F/C) zip up hoodie and sat in a chair  near the door.

Knock knock.

I dashed over to the door and flung it wide open, revealing the small purple haired boy. He leaped up at the sight of me and clung to me, sobbing his heart out. I shut the door, with him still clinging to my body and sank to the floor hugging his skinny frame. He sobbed into my chest and I sobbed into his purple hair.

Last night I woke the fuck up, I realised I need you here as desperate as that sounds, yeah (x2)

He calmed down and looked up at me with his big, innocent, purple eyes, which were red and sore from crying. His cheeks rubbed raw from wiping his tears so much. His lip quivering.

We live in an age where everything is staged, and all we do is fake our feelings.

"Oh Kokichi... I missed you so much!" I cried.
"But why did you miss me? I hurt you..." he mumbled. "I HURT YOU AND I CAN'T FORGIVE MYSELF!!" He screamed and buried his face back into my chest.

I'm so scared to put myself so out there. Time is running out, yeah.

"Kokichi..." I said softly, pulling his head up off of my chest. "I forgive you... it's okay... trust me..." he looked at me for a moment and nodded, hugging me tightly.

Need to let you know

Later

"You... got back with him?!" Kaede asked, completely baffled.
"But... that degenerate male cheated on you!" Tenko screeched.
"I... don't understand this..." Shuichi muttered.
"Well that was unexpected." Rantaro said quietly.
"I really don't understand why you're back with this bastard..." Maki stated coldly.
"HAAAAAAAAAHHHH?! YOU'RE BACK WITH THIS IDIOT?!?!" Kaito yelled.

That. Last night I woke the fuck up.

"Uh, guys it's not that big of a deal..." I faltered. Kokichi didn't say anything, he just hid behind me, shaking. He was terrified of what the others would say and do. He knew he probably deserved it to an extent, but who wouldn't be scared of your girlfriend's best friends when they're mad? I could hear him whispering 'I'm sorry, I'm sorry, I'm sorry' over and over again. He sounded like he was crying too.

"Kokichi! Get out from behind (Y/N) and face us!" Kaito shouted. Kokichi jumped and creeped out from behind my back. All five of them exploded in anger and were yelling and screaming at him (including Shuichi damn). They were all red in the face from the amount of screaming they were doing.
"STOP IIIIITTT!!!" I screamed as loud as I could. All of them fell silent immediately.

I realised I need you here as desperate as that sounds, yeah yeah.

He was distraught. He was shaking so much that he collapsed heavily onto the floor. His tears were silent besides from the odd hiccup.

"I-I kn-kn-kn-know wh-wh-wha-what I d-d-did was-s-s wr-wro-o-ong-g," he stuttered shakily. "A-A-And I-I h-h-h-ha-a-ate m-myself-f-f f-or i-it..."
I crouched down and scooped him up.
"Guys... you can go now if you want to..." I whispered quietly over my shoulder to the five of them. I walked away with Kokichi in my arms like a child.

Last night I woke the fuck up. I realised I need you here as desperate as that sounds, yeah yeah.

I laid him down gently on the bed and lay opposite to him, gazing at his tear stained face. He had worn himself out and passed out into a deep sleep. I closed my eyes when I heard him mumble something in his sleep.

"I'm sorry, (Y/N)... I love you so so much..."

I smiled to myself and fell asleep, ignoring the buzzes from my phone where the group chat ((Y/N), Amami, Shuichi, Kaito, Maki and Tenko.) was going crazy.

THAT WAS SOOOOO MUCH FUN!!! This is probably the longest oneshot I've ever written! Feel free to request songfics too if you want.
