A/N: I do not condone incest. This is just fiction. It will be a pretty short story so expect updates quicker. Also, I'd like to repeat that I'm still a learner in English so expect errors, and repetitive words. Also it seems that Liliya and Rozaliya still haven't been added to the character list in this website. I'll try contacting support.

Rozaliya arrived at the town square a quarter before 5pm. She looked around at the people milling about when a light December breeze sent shivers through her. Clutching the red scarf tighter around her she took out her smartphone while sitting down on a bench.

"Seems she's not here yet" she said while checking the time. "Ah well, it's still 15 minutes to go anyways"

She opened up her inbox to check the messages that she had been exchanging with the girl she had recently matched with on a dating site.

A light blush and a naughty grin etched on her face as she read her not-so-innocent exchanges.

"Blueberry_blitz-chan is so cute when she roleplays" Rozaliya giggled while scrolling through their texts.

It had been atleast a month since she had matched with Blueberry_blitz and they hit it off pretty well. Both were equally in need of love and had decided to meet up to celebrate the New Year together. They still hadn't shared any private info about each other but Rozaliya was hoping that would change once they met.

"It's been so long..." she reminisced as she gazed up at the gradually darkening sky. Lights were now being lit up around the square.

She had left the orphanage two years ago to pursue her dreams of learning art. Since then she had put her heart and soul into keeping herself busy with work and studies. Enough effort that she had spent the last two New Years all alone. But this time, she wanted to change that.

This time she wanted to spend it with someone she loved. She wanted to wake up in the arms of someone who loved her back.

Thoughts of a certain blue headed girl suddenly started intruding in her mind.

-( 2 years ago )-

Rosaliya closed up her suitcase after one last check. She was certain that everything she needed was packed and ready. She rubbed her hand across the smooth top wistfully.

"Alright. I'm done packing" she stood up and was about to leave the room when she came face to face with her younger twin sister "Liliya..."

"Cocolia-san already told me. She said you were going away to the city" Liliya spoke in her usual stoic voice but there seemed to be some kind of worry etched in there as well.

"Ah yeah... An artist saw my works and said she wanted to mentor me. She's quite talented so I accepted her offer. But her studio's in the city so, I gotta move there if I want to learn from her. I wanted to tell you but-" she paused with a sigh "It's been really awkward between us since that kiss hasn't it"

"I already told you. It meant nothing. I won that bet" Liliya said turning away.

"Yeah... but then why have you been ignoring me since then? Did I do something? Please just tell me..." Rozaliya paused, suddenly feeling heavy in her throat "I don't want us to separate like this"

Liliya said nothing but just stood there, facing away. The question remained hanging in the air unanswered.

Rozaliya reached out to her sister and put a hand on her shoulder "Liliya I-" she never got to finish as Liliya pulled herself away.

"Don't touch me. Please..."

She turned and ran out of the room leaving a shocked Rozaliya who could only listen to the footsteps fading away.

That night Rozaliya slept alone on the bed which the two of them had shared since they were little children.

-(Present)-

Rosaliya sighed as she recalled her parting with Liliya. The next day after that comversation, she had left for the city. Liliya never came to see her off at the station.

"It was all because of that goddamn kiss" Rozaliya thought bitterly "I never should've dared her"

It was just a harmless dare that Rozaliya had given to Liliya assuring her that it would mean nothing. After all, they were sisters weren't they? Twins no less. A kiss between sisters was alright wasn't it?

But that wasn't so. The sensation that had sparked with it still haunted her. The feeling of Liliya's soft, tender lips on hers still left her with longing.

"I fell for my own sister" Rozaliya buried her face in her hands "I'm terrible"

ring

Rozaliya snapped out of her thoughts as her smartphone started buzzing. Her breath hitched when she saw the caller.

"Oh, oh! Blueberry-chan's calling me! Alright this is no time to get gloomy" Rozaliya patted her cheeks lightly before accepting the call, all the while oblivious to the person who walked up behind her.

"Hello? Blueberry-chan? I'm already at the square! Are you nearby?" Rozaliya answered cheerfully.

"Sis?"

In her shock of hearing the familiar voice behind her, Rozaliya did not even realize that it came from her phone too.

Rozaliya whirred around and finally came face to face with the blue-haired girl standing wide eyed with an unreadable expression.

"Liliya...?" Rozaliya was speechless for a few moments as she studied her sister whom she had not seen or even talked with for so long. She had definitely grown in the last two years. She was wearing a brown long coat and jeans and seemed to have on jewellery and makeup as well. She had her hair in a bun and a blue scarf wrapped around her neck. 'Beautiful' was the only word that echoed in Rozaliya's mind

"After so long..." Rozaliya wanted to say more but she realised she was still on a call. "Ah, one second" She tried to return to her call but found that it was already cut off. "Crap"

"Liliya could you please wait a bit. I really need to make this call"

Liliya didn't answer but instead she opened a screen on her phone and showed it to Rozaliya "Sis...you're Molotov_Cherry?"

Rozaliya was about to call back her date but stopped mid-way when she heard her name she had set up in the dating site.

"Huh" turning to look at her, she saw what appeared to be texts on Liliya's phone. Taking a better look at them she realized, to her horror, that they were the texts she had sent to her date. And it finally clicked. The phonecall, Liliya coming at such an oppurtune moment.

"L-L-Lililya...y-you're Blueberry_blitz?" Rozaliya squeaked out, unable to form coherent thoughts anymore.

Both of them just stood there too shocked to even say anything while the same thought echoed in their minds

'Oh no'
