(Y/N is seen with Supergirl as they are about to enter in the Rock concert.)

Supergirl: So, baby... ready to have your face melted?

Y/N: If this has something to do with being in a rock concert... alright. I'm ready.

(Then they enter at the rock concert and see Ami and Yumi ready to sing.)

Ami: Ready?

(Song ends and everyone, including Y/N cheer Ami and Yumi)

Y/N: Oh yeah.

Supergirl: They're amazing.

(Then Ami and Yumi look at Y/N and make an announcement.)

Ami: For our next music, we will need an assistant.

(Then they see Y/N again)

Yumi: How about you?

(Ami and Yumi wink at Y/N as he realizes that he was chosen. Then he steps in the stage.)

Ami: What's your name?

Y/N: I'm Y/N L/N.

Yumi: Can you sing?

Y/N: Yes, why?

Ami: Could you sing a classic rock music you know?

Supergirl: Yeah, Y/N. Sing. Sing. Sing. Sing.

Crowd: Sing. Sing. Sing. Sing.

Y/N: Alright. I'll sing a rock music made by my favorite band Nirvana.

Ami: Drop the beat!

(Then the song "Smells like Teen Spirit" starts.)

Y/N: 🎵Load up on guns, bring your friends

It's fun to lose and to pretend

She's over-bored and self-assured

Oh no, I know a dirty word

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello

With the lights out, it's less dangerous

Here we are now, entertain us

I feel stupid and contagious

Here we are now, entertain us

A mulatto, an albino, a mosquito, my libido

Yeah, hey

I'm worse at what I do best

And for this gift I feel blessed

Our little group has always been

And always will until the end

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello

With the lights out, it's less dangerous

Here we are now, entertain us

I feel stupid and contagious

Here we are now, entertain us

A mulatto, an albino, a mosquito, my libido

Yeah, hey

And I forget just why I taste

Oh yeah, I guess it makes me smile

I found it hard, was hard to find

Oh well, whatever, never mind

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello, how low

Hello, hello, hello

With the lights out, it's less dangerous

Here we are now, entertain us

I feel stupid and contagious

Here we are now, entertain us

A mulatto, an albino, a mosquito, my libido

A denial, a denial, a denial, a denial, a denial

A denial, a denial, a denial, a denial🎵

(Then the crowd cheers Y/N up)

Random Person 1: You did well!

Random Person 2: Wonderful!

Supergirl: OH YEAH, BABY.

Ami: (in a flirty tone) You sing well.

Yumi: (in a flirty tone) We never knew such a good rock singer.

Ami/Yumi: You deserve a reward.

(Then Ami and Yumi kiss Y/N's cheek.)

Y/N: Thanks, Ami and Yumi.

Ami: (whispers in Y/N's ear) There's more where it came from.

Y/N: Well... The show must go on!

Yumi: Oh yeah. This time, three of us will sing a rock music together!

Crowd: YEEEEEEEEAAAAH!!!

(Music ands and the trio is cheered up)

Ami: (in mind) Handsome and talented.

Yumi: (in mind) He's got the talent. And his beauty is captivating.

(Some hours ago, Ami and Yumi call Y/N and give him their numbers.)

Ami: Whenever you want to have a private show with us, you just need to call us.

Y/N: Thanks.

Yumi: See you later.

(That's how Y/N showed his other talent. He proved to be a good singer.)
