(A/N): Thank you to Wine_And_Sad for suggesting I remake this old oneshot from my first book. I hope this is to your liking!

"This isn't funny, you two!" L shouts.

So, Misa being Misa, thought it was a good idea to trap both you and L in a box and leave you there. How this managed to happen, no one knew. All that was known was that no one liked it.

L was certainly not happy with the situation as his time, that he could've used to work on a case, was being used to sit in a box.

You, on the other hand, didn't like being trapped in this box, for a whole other reason...

It was cold. And claustrophobic in the box. This was not good at all.

L slumped down and folded his arms.

"No good. They just think this is some sort of joke!" He said.

Cold...Claustrophobic...

These things you knew too well...

"Are you alright (Y/N)?" L asks, noticing that you hadn't moved or said anything. "You're looking a little pale..."

No...You weren't good. You weren't good at all.

The whole fact that Light and Misa had thrown you in a box had brought back memories you never thought would come back.

Memories of your past...

The whole atmosphere around you had taken place once before, when you were a child.

"No..." You whisper, screwing your eyes tightly shut, hoping to make the memories vanish.

But once you opened your eyes, everything had changed.

A dark, cold room. Almost like a room inside a psychiatric hospital. Only four walls surrounded you. You clothes were ripped a little and your hands were tied.

"What's going on...?" You ask yourself, looking around.

Meanwhile, L watched you, confused for a second, before putting his focus back on trying to get out of the box.

"This is a room I don't recognise..." You whisper again. L couldn't hear you over the sound of him hitting the box to try and rip it open, as well as Light and Misa laughing from the outside.

You try and break free from the ribbon wrapped around your wrists, but they were still trapped.

"Help me...Mum...I'm scared..." Your sad, young voice pleaded as tears began to fall down your face.

All of a sudden, you felt somewhat safer as you see the door handle to your room go down and the door slowly open. However, your smile dropped when you realised it wasn't mum.

It was someone you didn't even recognise.

"Um...Where's my mum?" You ask the mysterious person who was dressed in all black, with a mask covering his face.

"She's no longer here" the voice of a man called to you.

"Wh...What have you done to her?!"

The man didn't respond and instead walked slowly towards you.

"Why am I here? Why can't I move my hands? What are you planning to do to me?!"

Still no response from this man.

You had to get out of here! Fast! You weren't safe here!

Immediately, you leaped past the man towards the door he came in, in attempt to escape. But you were soon stopped by the man grabbing your hair and pulling you back in, freaking you out and causing you to scream and snap back into reality.

L soon turned around at the sound of your scream and Light and Misa stopped laughing.

"Let me out! LET ME OUT!!" You cry, smacking your fist against the box. "YOU HAVE TO LET ME OUT!!"

"(Y/N)...?" L watched, terrified at what had caused you to react in this way. 5 minutes ago, you didn't have a care in the world for anything. What happened?

"ARE YOU GUYS EVEN LISTENING TO ME?! YOU HAVE TO GET ME OUT OF HERE RIGHT NOW!!" You continued to scream.

"Y-Yeah! Let us out!" L said. You were clearly not in a right state so you had to get out before anything else happens.

Confused and pretty scared, Light and Misa began pulling away at the top flaps of the box, pulling them open so both you and L could scramble out.

But you were too shaky to move properly and fell over coming out of the box. L went to make sure you were okay.

"What was that all about...?" Misa asked.

Light went to say something but was cut off by you weeping softly. L cradled you in his arms.

"Don't cry (Y/N). What's wrong? What happened?" L said, trying to calm you down.

You were too scared to speak. You just couldn't stop shaking.

"It's okay. Everything will be okay. I'm here. Let's just calm down, okay?" L stroked your hair, reassuringly. "Deep breaths."

"I'll go get (Y/N) some water!" Misa said and rushed off to the kitchen.

L just glared at Light.

"What the fuck have you done?" He asked him.

"Hey! Don't blame me! This was all Misa's idea!!" Light replied back.

"It wasn't just my idea!!" Misa states, coming back with a glass of water.

"Yeah it was! Because you're all about the romance and doing stupid stuff after L and (Y/N) announced that they were dating!" Light snaps at Misa.

"Why are you suddenly yelling at me?" Misa said to Light, giving you the glass of water. "I was only having some fun!"

"And now I'm getting the blame for making (Y/N) panic!"

"EVERYONE SHUT UP!!" You scream, spilling some of the water and making everyone turn to look at you.

"L, can we go to a different room please?" You ask him, with tears in your eyes.

"Of course" he replied, picking you up in his arms.

"We'll come with you" Misa called.

"No...I want it to just be L and me..." you say back to her.

Light and Misa watched as L carried you to your bedroom and layed you down on your bed.

"I'm sorry for scaring everyone like that..." You say sadly.

"You have nothing to apologise for" L said, rubbing your back.

"I just...I had flashbacks..."

"Flashbacks?"

"Of my past..."

"...I see." L looked down at the floor, unsure of what to do.

"...Do you want to talk about it?" He asked after a few seconds.

You took a deep breath and told L everything, explaining that the box made you feel unsafe because it reminded you of that room you were trapped in as a child and how it was dark and claustrophobic, much like the box.

L listened to every detail very carefully, without interrupting any part of it. His heart was breaking for you. He knew, himself, what it was like to have a tragic past and that it takes a lot of healing to grow past those wounds.

"I thought I had put it all behind me" you began to cry.

L wrapped his arms around you and pulled you into a warm embrace, resting his chin on your head.

"You will someday, (Y/N). You will. I know you can" L said, holding you in a gentle way to not scare you and to be reassuring.

"Do you know anything about the man who abused you?"

"No..." You whisper. "I don't know his name and he was wearing a mask so I can't tell you what he looked like either..."

"...."

"Maybe having a lie down can help?" L suggested and you nodded, getting under the covers.

L stroked your hair again.

"I can leave you to rest" he said, standing up.

"Can you stay here? Just until I fall asleep?" You ask him. "It'll be easier for me to get some rest if you're here with me."

L smiled at you and sat back down. "Whatever you need."

After a while, you were fast asleep. L kissed your forehead and made his way out of the room to let you sleep.

As he made his way back into the living room, he saw Light and Misa staring at him as if they were waiting for him to come back.

"You guys are sick! How could you cause (Y/N) so much pain and trauma like that?! You should be ashamed of yourselves!" L snapped at the two.

"We're sorry. We didn't know it'd have such an affect on her. It was just a joke" Misa said.

"A joke? You need to stop and fucking think before you act next time!"

"We're really sorry. Is she okay?" Light asked.

"She's resting" L said. "Now, if you'll excuse me, I have stuff to do." He walked straight past the two and went to his room full of computers.

"I'm going to find that man, whoever he is. Even if I have nothing to go on, I'll do what I can to track him down. I will not let him roam free after causing all this suffering for (Y/N). I will find him and make sure justice is served" L said and sat down in front of one of his computers.

"For you (Y/N)."

(A/N): I hope this was okay. It was a bit of a challenge but I tired ^^;
