You and Sans were inseparable on the phone since that Monday night. By the time Wednesday came around, you felt like best friends.

"Best friends...but I still want more than that!"

This voice has driven you insane, but you've learned to cope. Even though you gave your best effort to ignore these dreaded thoughts, they still seemed a little truthful. If you were to be quite honest with yourself, you couldn't help but get lost in the words your mind through at you. You even swore there was a hint of familiarity to these feelings, but you had just met the skeleton. It made no sense to you.

That was a question for later. Your phone buzzed, the familiar ringtone of "Life is a Highway" boomed throughout your room, causing you to jump. You looked at the ID and smiled. You answered casually. "Yellow!"

"Yellow to you too, _____! Today is the day, but I think I have something else in mind. Meet me at the park in an hour, and stay near the duck pond. I'll find you!" Sans said. You were eager to see this surprise Sans had in store for you.

"Sounds fun, dude! See ya then!" You say. You hang up and look in your closet.

"Find something a little decent at least!"

"Oh shut up!" You say aloud.

"Just do it! Being a little dolled up is okay, right?"

"Ugh, fine! Whatever!" You say.

You put on a white tank top and then looked through the somewhat dressier side of your closet. You found and put on a white mesh top that flared out at the bottom, the cotton so comfortable as you slipped it on. You spun for the fun of it, watching the shirt spin with you as it resembled a tutu. You got a little dizzy and laughed at your random antics.You picked up a three quarter length sleeved pink floral patterned light jacket and donned the springy article. Then you put on navy blue skinny jeans and faded brown colored boots that rose four inches above your ankle. You donned the outfit, admiring the simple yet beautiful look of yourself in the mirror. You fixed your hair into a comfortable yet semi-elegant style and put on a diamond and silver necklace that was given to you by your grandmother when you were young. Her words rang in your ears.

"Now, ____, wear this for someone very special!" Your grandma said to you. Your ten year old mind rushed to your dad or mom, but as you grew older, you soon realized it meant something else.

"Is it really worth it? I mean, is Sans really that special to me?"

You couldn't shake the feeling that he was that important and special to you. He made you happy, he made you laugh and smile. He made you feel....alive! He made your day every time you so much as heard his name.

"I-I can't believe it! I've fallen for a skeleton!" You say. You finish getting ready and drive over to the park. You smiled as you walked about the peaceful park. The lush green grass and colorful fall leaves filled you with DETERMINATION! You sat by the duck pond, even taking the time to feed what few ducks still remained in the pond. You almost didn't notice when you started humming Elvis's "Can't Help Falling In Love" as you did so. You also couldn't notice how you whispered the lyrics to yourself. Sans snuck up on you, but stopped before he would. He heard your singing as he joined in, startling you. His deep voice resonated in your head, soothing and relaxed. It was like taking a sip from a (favorite flavor) cold medicine when you were sick as a kid. It made you feel better and it's silky texture made that feeling multiply. You both sang along together smiling all the while.

"But I can't help falling in love with you!" You both finish off. It was a sweet moment that caught you slightly off guard, but it made you happy that Sans was so willing to join whatever you were doing. It filled you with....DETERMINATION!

"_____, I didn't know you sang so well! That was beautiful!"

"Heh, thanks," you reply, your face becoming a delightful shade of pink.

He wore a tuxedo patterned tee underneath a light jacket in a shade of blue. He had on black jeans and blue sneakers. You grinned a bit.

"What's the getup for, bone head!" You say.

"I could ask the same about you. Now hold my hand, and don't let go," he said. You grab his bony hand and you see his eye glow blue. You didn't know what was happening, but you felt dizzy. The world was spinning!

When it stopped, you were in a cavern. Small glowing blue mushrooms decorated the ground. You see a blue flower and walk over to it.

"Hello, I am an echo flower! I repeat the last thing I heard!" It said to you. The voice was of Sans. You approached the next one, it said, "this is Sans. You may have guessed by now though."

You smile. Either you were on a crazy drug trip or you were in the fabled Waterfall Sans had told you about. You kept jumping from flower to flower, getting a sort of spoken letter.

"_____, I don't know how to say this, heck I don't even know if you'll like me after this..."

"But I decided that you never know unless you try right?"

"Anyways, I find my rather nonexistent heart skip a beat or two when I see you!"

"Your (eye color) eyes fill me with enough determination to take on the world alone!"

"You light up my life. You make me happy!"

"I only want the same for you, ____."

"You probably have guessed where you are, right? Waterfall. Well, this shows how much I've fallen for you."

"I've waterfallen head of heels for you, and if you don't feel the same..."

"I'd understand..."

You gasp. You look around to see no sign of Sans anywhere. You keep going with your flower hopping.

"I mean, who would date a skeleton monster like me, anyways..."

"ME SANS! ME!!"

"Why would such a beautiful and talented human such as yourself get caught up in my nonsense..."

"BECAUSE I....I...."

"I...I love you ______. With all my soul! I hope there's a happy end for us, but if not, then I suppose we could just stay friends, unless you don't want to..."

"I...I..."

"Then I could leave you be forever..."

"No...I love you too Sans!"

Those words hung in your mind. You sat down. You listen to some other echo flowers, but they were just passing conversations. You had an idea. You whispered thoughts to them for Sans to find. You ran off after your message was said to find Sans. He was next to a telescope leaning against the wall. You heard the distant waterfalls, which filled you with...DETERMINATION!

"H-hey Sans!" You said. He jumped and went blue faced.

"H-hey, •___•! D-did you..."

"Yes I did. I in fact, wanna show you something I found though!" You say, grabbing Sans' hand and dragging him along. You knelt down next to your first flower.

"Heh, just another echo flower kid!" He said.

"Listen to it!!" You say. He rolls his eye sockets and listens to the message.

"Dear, Sans..." It started. He looked confused and he did some flower hopping.

"I heard that you liked me, so I decided that if make your day!"

"Turn around...see the surprise yourself, I bet you'll like it!" He turned to have you grab him and hug him tightly. He hugged you back.

"I-I love you too Sansy!" You say, "You're my precious waterfall!" You continue, making the skeleton very flustered. He looked at you, his white pin pricks of eyes shrunk to the size of pins. His face was purely blue at this point.

"S-Sans? Hello?" You say, tapping him. He gasped and held you tightly, sobbing happily into your jacket. You hugged back and let him hold you. You could feel his ribs digging into your skin, but it wasn't uncomfortable. In fact, you kind of liked it. You smiled and told yourself that it definitely wasn't going so bad after all!

Okay since you guys couldn't get your heads outta the gutters, I fixed it. Happy now? Cause I'm tired of explaining why I put it there!

Made a few minor adjustments since I went overboard on the "decent" clothes. XD tbh you can imagine anything you want, but this is a default. I actually have that outfit and may go and take a pic of it to give you a reference as to what you were wearing. I adore that outfit and wear it whenever I can (well, now it's my Undertale airbrush shirt and navy blue shorts XD)

Hope you guys enjoyed this. I'll be tweaking a few things for this story to make it a little better. Grammatical errors, spelling errors, all that jazz. Maybe even changing some wordings and scenes just a bit to help, especially in the earlier chapters. Welp, have fun! And newcomers, I hope you like the story! :3

This is the outfit (there is a white tank there below the top XD)
And don't mind my bro's legs in the background XD

The voice in your head is NOT Chara! It's your own thoughts.
