Noire's POV

I woke up after having a dream about Y/N and getting married, why did I fall for a guy like him? I got up, got dressed, and walked into the living room I saw Uni making breakfast with Lucy while Y/N was playing a game on his phone while Pico was waiting for the food to be done.

Y/N: *Playing a game* C'mon Sonic! You can do it!

Pico: Hey Lucy, how much will it take to be done with breakfast?

Lucy: Right now!

Y/N: *Looks up* Wow, this looks very good!

Uni: *Blushes* You really think so?

Y/N: Yeah! I can't wait to eat it!

Y/N and Pico started eating while Lucy took Uni and me to the side to speak with us about something. 

Lucy: So Noire, are you planning to take Y/N on a date soon?

Noire: N-No!... maybe.

Uni: He is cute and kind-hearted.

Lucy: Well, I'll let you go on a date with him today, and don't worry I'll tell Y/N about me sharing with you and the others.

I blushed after hearing Lucy say that I could have a date with Y/N. I looked over to see that Y/N was finished eating and I walked up to him.

Y/N: Oh, hey Noire, what's up?

Noire: *Mentally* OK, stay calm down. Just ask him out. *Out loud* Do you want to hang out with me today?

Y/N: Sure! What do you have in mind?

Noire: Well, that's a surprise... Don't think of this as a date!

Y/N: Don't worry, I'm already dating Lucy and I won't cheat on her.

Noire: *Mentally* Is he that dense?

Y/N's POV Timeskip

I was waiting for Noire to get ready, while I was waiting, I was listening to music and I liked one song named "Again".

???: I'm ready.

I looked up to see who I think is Noire but her hair was white and had blue eyes wearing a black dress. 

A/N: Ignore the sword.

Y/N: Is that you, Noire?

???: Yes but call me Black Heart, you should feel honored that you get to see me in my HDD form.

Y/N: Why are you dressed like we're going on a date? We're just hanging out as friends.

Black Heart: That's a secret. Let's just go.

Black Heart takes my head and we had Ice Cream, played some games in an arcade, and we were about to watch a movie but Black Heart was eyeing a cosplay store.

Y/N: Black Heart, are you eyeing that cosplay store?

Black Heart: *Embarrassed* W-What?! N-No! Not at all!

Y/N: I'm not judging you, in fact, Lucy and I went to an anime convention and I dressed as my big sister who's an idol.

Black Heart: *Interested* Your sister? Who's that?

Y/N: Her name's Miku. She's the one who got me into music. Here's the photo of when I dressed up as her.

I showed Black Heart the photo of when I dressed up as my sister and I could swear I saw her smile.

Black Heart: *Giggles*

Y/N: So, you do like cosplaying?

Black Heart: I...fine, I do. Don't you dare tell anyone, got it!?

Y/N: My lips are sealed.

Black Heart smiles and we go into the store. She was getting a few costumes while I played some games on my phone, after a while, Black Heart came wearing what seemed like a princess costume. 

Black Heart: How do I look?

Y/N: Very beautiful.

Black Heart: Let's get you into a custome.

Y/N: Huh?

Black Hearts grabs my arm and drags into a changing room with a costume that I recognized from my world. I dressed into it and showed Black Heart to see what she thinks.

Y/N: How do I look?

Black Heart: Handsome.

I blush a bit but smiled, after dressing into different costumes, Black Heart and I returned to Basilicom and before I could go to my room Black Hearts grabs my wrist.

Y/N: *Confused* Black Heart, what's wrong?

Black Heart: I was wondering if you could... *Whispers* sleep with me... 

Y/N: What was that?

Black Heart: If you could sleep with me tonight.

Y/N: I guess. But as long as Lucy is ok with it.

Lucy: I'm ok with it, Y/N, so don't worry.

I turn my head to Lucy smiling with Pico but Uni had a pouty look on her face but I ignored it.

Y/N: I'mma just wait for you to take a shower while I do the same, alright?

Black Heart: Ok.

Black Heart lets go of my wrist and I walk to my room to take a shower until I remembered how my sister must be worried about me. 

Y/N: I wish I could tell Miku that I'm ok. Should probably ask Histoire if there's a way to communicate with different worlds when we get to Planeptune.

After I finished taking my shower, I made my way to Noire's room to find her in her human form wearing her sleepwear.

Y/N: I'll look away to not make you uncomfortable while in bed.

Noire: I don't mind.

I lay down and closed my eyes but I felt Noire hug me. All I could do was hug her back before falling asleep.
