You were sitting in an echo tree as you tuned your guitar. You had actually ran away from home since your mom wanted you to marry some wolf monster you barley knew. You just wanted to grow up to be a guitarist and maybe work with Mettaton. You finally found the perfect tune for a song your dad taught you to play before he died. You strummed the strings gently before your (fur/c) tail swayed from the branch you were on.

The sun goes down
The stars come out
And all that counts
Is here and now
My universe will never be the same
I'm glad you came

You cast a spell on me, spell on me
You hit me like the sky fell on me, fell on me
And I decided you look well on me, well on me
So let's go somewhere no one else can see, you and me

Gaster, one of the royal scientists, was walking around when he heard you singing and playing the guitar. He wondered around until he saw you in the echo tree.

Turn the lights out now
Now I'll take you by the hand
Hand you another drink
Drink it if you can
Can you spend a little time,
Time is slipping away,
Away from us so stay,
Stay with me I can make,
Make you glad you came

The sun goes down
The stars come out
And all that counts
Is here and now
My universe will never be the same
I'm glad you came
I'm glad you came

Unknown to this skeleton, you actually had a little crush on him. Your (fur/c) ears and tail shined in the echo tree's light, as well as, your (h/c) (h/l) hair. Your leather jacket reflected the light as your jeans matched the blue glow.

You cast a spell on me, spell on me
You hit me like the sky fell on me, fell on me
And I decided you look well on me, well on me
So let's go somewhere no one else can see, you and me

Turn the lights out now
Now I'll take you by the hand
Hand you another drink
Drink it if you can
Can you spend a little time,
Time is slipping away,
Away from us so stay,
Stay with me I can make,
Make you glad you came

The sun goes down
The stars come out
And all that counts
Is here and now
My universe will never be the same
I'm glad you came
I'm glad you came

Gaster walked over and stood silently under the tree. He even smiled as you played the song.

I'm glad you came
So glad you came
I'm glad you came
I'm glad you came

The sun goes down
The stars come out
And all that counts
Is here and now
My universe will never be the same
I'm glad you came
I'm glad you came

You finished the song with a string strum before smiling to yourself. Your ear twitched as you heard somebody knock on the tree. You looked down before blushing. Gaster smiled and waved to you before you placed your guitar in between two branches and hopped down.

"I never knew you played guitar." Gaster admitted, you shyly scratched the back of your head as your ears twitched. Gaster noticed your tail was swaying faster than when you were playing the guitar. "Y..yeah! I.. um.. I..." You glanced away from Gaster's gaze before he snickered and kissed the side of your head, leaving you blushing like no tommorrow. "That's cute."

You blushed before you climbed up the tree and grabbed your guitar before hopping down again. You both sat under a tree as you played a random soft tune on your guitar.
