And here the next one! I hope you all enjoy this one as I feel like these two could be good friends if they ever did meet.

Simply how Shuichi is so kind and how adorable Mahiru could be.

And this is AU to canon, which mean Despair is still a thing somehow.

No really, I try to write that out. Meh, whatever I guess.

So, let start this!

And I hope you notice a pattern by now.

Shuichi Saihara and Mahiru Koizumi in...A smile in our darkest hour.

Shuichi wasn't sure he did the right thing.

He never doubted his deduction that his uncle taught him, but now he is.

And the reason is because of the person in front of him.

"Sato would never do such a thing!?" Mahiru Koizumi, his classmate from the same year, shouted at him angrily.

"I understand why you think that Ma-Koizumi. But all the evidence pointed to her and I try to look at all angles to make sure it wasn't her. But everything add up. She have no albi, her prints were on everything and not to mention, she have a motive. I'm sorry Koizumi, but Sato kill Natsumi." Shuichi said as he stare Mahiru in the eyes, refusing to lie to her.

Shuichi hated this.

Mahiru and him were on good terms with each other and were actually good friends.

But right now, it seem like he lost that for doing what he have to do.

He need to make sure Sato get her do and give closure to the Kuzuryuu family that their daughter murderer is going be away for a long time.

He BARELY stop Fuyuhiko and Peko from getting revenge and let him handle it.

He have scars from trying stopping Peko and if wasn't for Kirumi, he would be in the hospital or worst.

But the fight between Kirumi and Peko was a long one with Shuichi trying to convince Fuyuhiko to stop the fight.

After promising he will make sure the killer get their justice and to put fate in him, he order Peko stop attacking.

A good thing too since Kirumi was worry she may have to kill Peko to protect her Master.

Who knew a battle between Services was so deadly?

Anyway, ever since then, Shuichi had done all he could to find evidence and alibi's on who the killer was and was sadden when it all lead to one person.

Which brought him to get the polices to arrest Sato and they just took her away to be brought to court for a later date.

Which brought him to now.

"Please Shuichi! There got to be SOMETHING you miss!" Mahiru beg him, tears in her eyes for anything that can prove her best friend innocent.

"Koizumi...I'm sorry. I did all I can. All there is to do and wait for the court to decide what her punishment will be." Shuichi said sadly.

Mahiru eyes widen at those words before they were fill with angry.

A loud smack echo the room the two were in and Shuichi fell to the floor with his hat knock off.

Mahiru blink a few times as she Shuichi on the floor, his cheeks were a deep red and her hand stretch out.

Mahiru connected dots and her eyes widen in horror.

"S-shuichi I-i didn't me-." Mahiru started, but she was cut off by Shuichi putting his hand up.

"I need to go. I have to talk to the Prosecutor for this case. Sorry Koizumi. But this where we part ways for now." Shuichi said softly as he pick himself off the ground and left.

Mahiru started to cry as she realize what she just done and all her emotions finally caught up to her.

Mahiru just wail for a long time and didn't stop til she was on the ground hugging herself.

She manage to regain her bearings long enough to wipe her blood shot eyes and sniffle a little.

Mahiru look to the side and saw Shuichi hat.

She pick it up and stare at it in regret.

She struck her friend who try all he can to prove Sato was not the killer and stop Fuyuhiko from doing something that he would never get back from.

Mahiru wipe her eyes and put on the hat.

She blink on how low it was.

'So Shuichi never look me in the eyes.' Mahiru thought with a grimace.

She swears she will apologize and give him his hat back.

But for now, she got to give him space.

(A few weeks later)

Shuichi was in the park laying the grass staring at the sky with a blank expression.

Sato was now behind bars for some time, the Kuzuryuu family were thankful for his help and give him a reward and name him friend of the family, which means he part of the family appeartly, Fuyuhiko thank him from saving him and Peko from crossing the line.

Everything is fine now. Or, at least SHOULD be fine.

But Shuichi wasn't thrill about how this turn out.

Sato parents yell at him for wrongly accusing their daughter and the father actually try to punch him the face.

But Kirumi and Peko made him regret that.

And then the Resver course.

They hated Shuichi for using his talents to 'setup' an innocent student to cover up for a 'bitch'.

And their Mahiru.

He pretty sure he lost a good friend forever thanks to this case.

Shuichi touch his cheek and sigh.

The look of pure hatred in her eyes was too much to bear.

He figure she didn't want anything to do with him anymore.

So he left before she finish whatever she was about to say.

Shuichi faintly wonder why she wore his hat though at the trail.

Shuichi close his eyes and let the sun rays hit him.

Shuichi let the sound of the wind lull him to a much needed sleep and his world turn dark.

Shuichi open his eyes and saw Mahiru petting head as he had his head on her lap.

'Ah, I'm dreaming. There no way Mahiru would this for me.' Shuichi thought as he was pretty sure he was dreaming.

"Mahiru? I'm sorry." Shuichi said, decided to at least pour his heart here if he can never say it in reality.

"for what Shuichi?" Mahiru ask in surprise.

"I hurt you. I fail to be your friend and I hurt you instead. When you smack me, I was so sadden that I hurt you enough for you to do. I'm sorry. I'm so sorry for hurting you like that." Shuichi said as tears were in his eyes.

Shuichi felt drops fall on his face and look up to see Mahiru had tears in her eyes.

"Shuichi. I should be the one apologizing, not you. You done nothing wrong. You stop Fuyuhiko from doing something that he would regret for the rest of his live. You manage to give Natsumi family a peace of mind and you manage to make sure Sato got what she deserved. It hurts to think that way, but I know you did all you could and even went beyond your job as a Detective to help everyone involve in the case. I had no right to hit you like that. I was in the wrong, not you. I'm sorry for hitting you and making you think I hated you." Mahiru said as tears were falling on Shuichi face.

Shuichi was stun.

This was too emotional for a dream.

Could this be...

Shuichi lifted his hand and touch Mahiru face, wiping away the tears.

"It okay. I forgive you." Shuichi said softly.

Mahiru said nothing as she let more tears fall from her face and Shuichi smile.

'Yeah. This is real.' Shuichi thought with a soft smile as he kept wiping the tears away.

(Later)

After Mahiru and Shuichi got that out of their system, they just stay on the spot.

Shuichi was still on Mahiru lap and Mahiru kept petting his head.

They stay their, staring at the sky in wonder of the future.

They wonder if things can go back the way the always had it.

But one thing that will be for sure for them.

They will always be there with a smile for each other in their darkest hour.

This they swear.

And done.

I wasn't sure how well this turn out, but I think I did a well enough job with this one.

I try to be detail of the events that had appear for this and how both the characters feel about this whole the case to the best of my abilities.

Anyway, I hope you all enjoy this and leave a review if you can. They help me more then you think.

Anyway, I'll see you all on the flip side! See ya!
