Y/N walked Ariel towards the sidewalk today was the party, and everyone is going to be there. As both of them walked towards the house, Ariel spotted Miku walking with her boyfriend...She looked sad a little.

Ariel
"Kiss me Y/N".

"Wait what?".

Ariel
"Let's make Miku jealous, kiss me now!".

"I think you having to much fun with this...".

Ariel
"Kiss me you fool!".

"Stop, your scaring me".

Ariel pouted and just hugged Y/N, Miku noticed, and became a little agitated from the sight.

Miku - Mumbling
"Why are you hugging him...".

Several hours passed, everyone is now at the party​, and everything is in full swing.

Everything was going to plan..

Miku kept looking at us, she seemed unhappy with her boyfriend. Ariel kept playing and hugging me for the entire time.

Miku - Mumbling
"What does Y/N see in that little dwarf?".

Several people crowded around us, and begged me to play a song for them. Ariel tugged my shirt, and asked me to play Miku's favorite song.

"Alright, who has a piano?".

[Again- Your lie in April]

Y/N began playing, everyone stood silent for the Bard as he played. Ariel turned red, and sat down next to Y/N.

Miku eyes narrowed, she frowned, this is her song, why is her best friend playing this song for some girl, and not for her.

Miku thoughts
Why am I acting like this, I don't like my best friend...But...

I don't want him to have a girlfriend​, I don't like the thought of him being with someone else, it bothers me that he is spending time with someone​, and not me.

What does he see in her, some little icky dwarf.

Ariel leaned against Y/N's shoulder, making Miku even more mad. Miku's boyfriend went to the restroom. Miku didn't want to see this, she walked away, trying her best not to lash out.

Y/N has successfully made Miku jealous...Maybe even to much.
