After that they begin to stare at stars again with no worries on they shoulder, but Sans... did you know that you give her a most terrible idea that he could think... and he gonna regret that.

That day, Frisk told Sans to come to the beach at midnight, she said she want to show something to him. Sans was curious, because never once she told him to comeback on her own, usually Sans is the one who randomly come and visit her every now and then.
The sky is clear that day, Sans can easily see the twinkling stars that him more than enough light to see. With no reason Sans suddenly feel very excited and decide to teleport himself to the isolated beach. Frisk already there, waiting him with huge smile on her face, her tail swing back and front showing her excitement.

"Yo kid, what do you want to show me?"
"Not here Sans, it's in underwater!!"
"But.... i can't swim... and you know that right"

Frisk giggle seeing Sans disappoint expression, and take his hand.

"You have me you know, i will never let you go, trust me okay, beside i want to celebrate because tomorrow i will try facing human!!"

Sans nodded but then yelp when she pull him to the water, luckily he not choked thanks to his nonexist lungs. Frisk keep pulling him deeper to the bottom of the sea, Frisk gently but firmly hold his hand, never lying when she said never let him go. Dark, even Sans can't see anything in this point, seems like they are already very deep in the water that even a moonlight can't reach.
Suddenly Sans feels that Frisk stop swimming, he want to ask but unfortunately he can't speak in the water. Frisk grip his hand answering his silent questions.

"Don't worry Sans, wait a bit okay"

Sans forgot she is a freaking mermaid, of course she can speak under water, and he don't know if she can see him in this point or not but then Frisk hold Sans closer to her, not just close but now she hugging his arm. Sans blush light blue color that shine in the dark, and with that he can see Frisk stare at him in awe.

"Woah... your face is glowing!! are you alright Sans?"

Sans can't do anything than cover his face with his free hand, but not enough to hide his glowing blue color on his cheek.

"Are you... blushing? you look very cute!!!"

Embarrassed, Sans give his last attack, he pinch her cheek until she struggle to break free from Sans grasp, but because of that Sans lost his connection with her hands and begin to panic because he simply can't see anything. He want to call Frisk but he can't speak, his body freeze with fear and his demon inside him begin to speak in his mind.

"No one love you.... you are alone..... no one gonna save you.... you will trapped in darkness forever.... you are unless... good for nothing.... you are trash.."

That voice keep repeating again and again, Sans really want to scream but he can't. He grip his head with fear and begin to trembling slightly. Suddenly a gentle hands hugging him, made the voice inside his head gone in instant and replace by a shooting voice, he can feels a light pats on his back trying to comforting him.

"I'm sorry... it won't happen again, i promise... I'm with you... calm down okay"

Sans grip her clothes like his life depending on it, but he alredy calm enough to stop shaking. Frisk cover Sans eyes, of course it's not effective because he already can't see anything.

"Focus to my voice okay, don't think anything else but my voice... you gonna be okay, i promise, i will protect you"

Sans can't help but feel something inside his chest moving trying to tell him something that he already forgot long ago. Frisk release her hands that made Sans uncomfortable, clearly carving for her touch. But what he saw next stunning him, light.... many light floating around him... colorful and beautiful, gently dancing with one another creating a faint glow everywhere.

"This... is what i want to show you, they are my stars and my light in this dark world, you the first person that i want to share my precious secret"

Sans stare at thousands of jellyfish that swimming around with many different color, but what made him froze is Frisk...
She float beside him, with genuine smile on her face, the light create a beautiful effect on her make her glow. Sans heart begin to beat faster and faster, making him realize something that he feared the most. He alredy fallen... he fallen for her and hard!

He grip his cloth where his heart suppose to be when it's keep telling him to confess.
But his fear of rejection win and push his growing feeling back 'No.. i don't want to ruin this... what if ahe doesn't love me back?' (A/n : NONSE!!)

He keeps repeating those sentence over and over again until they back to the surface, when he want to teleport himself back home. Frisk hand him a letter saying he only can read it tomorrow and then she's gone, leaving confused Sans behind.
