Something Old... Something New.(pArT uNo)

Hello, Potatoes.

Thats all i got....  OKAY ON WITH THE STORY!

Frisk was sitting at her dresser, brushing her long brown hair. It's been years since she first fell into the underground. Tomorrow would be her 19th birthday and the eleven year anniversary of her fall. Technically, it was just the anniversary of when she had fallen, but it was celebrated as her birthday. When she had fallen, her mother, Toriel, had convinced her to stay. The ruins have become.. Rather small, but she enjoyed them. She had even managed to befriend a certain Flower over the years.

"I still don't get why you don't just leave, Frisk. She'll never willingly let you go..." her flower friend spoke to her.
"Because, Flowey, I'm old enough to take care of myself and she knows this. She was just nervous before because i was really, really young. And I'll bring you with me so she definitely doesn't have to worry!"
"Fine," he grumbled.

Frisk put on a lovely blue sweaterdress with magenta stripes on it and her black leggings. The sweaterdress was a bit too big and it slid down one of her shoulders to show the sleeve of the black tanktop she wore underneath it. She loved it though, because her mother made it for her. She let her long hair flow down instead of putting it up today.
She normally would keep it cut short, but her mother loves it long so she keeps it that way for her mother to be happy. It doesn't bother her too much anyways.

She smiled at her Flowery friend as she picked him up and walked to the living room, where her mother rested in the chair with a gift bag beside her. She was waiting for Frisk to come out so she could give the present to her. "Ah, my child! I see you have awoken and gotten ready. You look so nice, dear. I'm glad it fits you so well," Toriel's soft voice rose just as she did from the chair.
Frisk giggled a bit, "Yes, mother. Thank you for making it, i really love it."
Her mother smiled and hugged her, "Of course, and happy birthday!" she handed Frisk the bag, "here is your present my child!"
"Thank you, mother" Frisk smiled and began to open it.
What was inside was a music box. The music box was painted black and had a small, red heart you had to press to open it and make the music play. Inside was a ballerina that spun with the music and space to put little objects such as jewlry or hairties, things of the sort.
The music was a haunting tune, haunting as much as it was beautiful. Frisk smiled, enjoying the haunting melody.
[*A haunting melody echoes throughout the corridors.
  *won't you play along?]
Even Flowey seemed to enjoy the lovely tune.
"Thank you, mom!" Frisk hugged her beloved goat mom, "but.. May I ask you a question?"
"Of course, my child."
"M-May i... Venture out of the ruins, today?.. I'm 19, mother, the ruins are getting small and i can take care of myself. Please?"
"...my child...." Toriel sighed, "Alright..."
