Frisk… Please… help me…

The young girl bolted out of bed in a cold sweat. Her dark brown hair was stuck to her forehead and her eyes darted across the room. Impatient small hands grabbed at the air but there was nothing, there was no one.

"Asriel… I- I'm sorry…" her voice came out, fragile and wounded for it was Frisk's tender heart that never truly let go of thinking about him. It had been six years since the monsters had been freed from the underground but she knew he was still there.

"I'm sorry I couldn't help you… I'm sorry I was a bad friend." Frisk's voice quivered as she rolled up into a ball and cried. For a while there was silence along with her small sobs but soon the door creaked open and blue light entered the room.

Frisk knew who it was before he could speak.

Sans.

"I had the nightmare again." She sat up and stared at him, biting down on her lip to keep from crying. Frisk hated crying though she did it often, especially with her teenage hormones flying all over the place.

Sans nodded slowly making no comment about her tears as he closed the door behind him and walked over to her bed, sitting on the edge. He pulled out his hands from his pockets and started whistling a soft tune. "It's going to be alright kid. You're going to be alright." His gentle voice reassured Frisk that everything was okay. But deep down she knew it wasn't.

"Sans, I miss the old days." Frisk mumbled sleepily as she began to close her eyes slowly. Her eyelids fluttered and she let her head fall on the pillow, not yet asleep.

"Why? I prefer the New Days, they're hipper." His joking tone relaxed her and she let out a tired chuckle.

"Goodnight Sans." Her voice wavered and after a while Frisk fell into a calm sleep, the melody encircling her mind.

Sans watched her with a pained expression. He could tell she wasn't alright. He could see it in her eyes because he saw it in his own every morning, every night. There was this desperate need to comfort her lingering inside of him but he pushed it away. Unfortunately she was growing and so was his l-

The word disgusted him.

It meant so many different things. Up here it was a deep affection shared between two people and down there it had been the level of violence one could commit. And yet it could cause so much damage to humans as well. He had seen it tear up relationships in a heartbeat, watched what jealousy drove others to do. It disgusted him.

With a grunt, Sans stood but Frisk mumbled the words stay which made him sit back down, his short legs dangling over the bed.

He thought of Frisk's height and laughed quietly.

The girl had certainly grown over the years. She was now his height and yet never really outgrew her sweaters. Frisk was still very kind though except she was very distracted and easily lost interest in many things, one of the main reasons why she had problems in school. Alphys had, thanks to Sans, gotten the idea to home-school her so that she spent all her time with them, with him. These selfish thoughts made him think twice about his feelings but he just knew he wanted to make Frisk happy. She and Papyrus were his biggest concerns though the love was different. Papyrus had a close family bond. But Frisk… she was different and the feelings he got with her were a bit more… strange.

Snore.

Sans jumped at the sound of her snoring and then mentally laughed. Oh Frisk, he shook his head and patted her hair before he left down the hallway. At least she had fallen asleep, the nightmares were getting repetitive and it worried him that it might be because-

"What were you doing in there Sans?" Undyne smirked at the skeleton brother showing her glossy white fangs. Her head was wrapped up in a towel and she smelled of soap.

"There? I know of no such place." He shook his head as if the question was absurd.

Undyne merely laughed and shook her head. "Don't act a fool Sans. And don't think we haven't noticed what's going on." Her smirk widened into a grin and she walked off to her room.

The skeleton mumbled a comeback but was too tired to really quarrel. He needed to get his rest because tomorrow was Frisk's birthday and he planned on making it her best one yet.

Frisk was awoken by the gleaming sun rays that poked through her lavender curtains as she slowly stretched upwards. Her eyes were half open- half closed and she had no recollection of last night's events nor did she want to have because Frisk did not like sad things.

She let out a light gasp and turned her head to look at her clock.

8:01 a.m.

"It's here..!" She cried happily jumping out of bed and lacing up her muddy maroon colored boots. They matched her many striped sweaters and she never went anywhere without them.

Today was Frisk's 16th birthday and boy was she excited. Usually her friend's from the Underground went out of their way to make the day special so she was looking forward to today's surprise.

Maybe they'll take me out today… she grinned and rushed out her small footsteps stomping on the ground as she jumped down from step to step loudly, as if to allow them to hear her presence.

"Good-" She stopped once she surveyed the scene around her. It looked… average?

Papyrus was at the table rambling about something from his cereal box, Asgore sat drinking coffee and reading a newspaper, while the girls- Undyne and Alphys, were gushing about some character from an anime. Frisk looked hopefully over at Toriel whom was serving everyone pancakes. Sans was usually the last one at the table so Frisk didn't bother looking for him.

"Um, good morning…" She spoke up a bit shyly. Only Papyrus looked up and gave her a big grin. "HUMAN! THE SUN HAS RISEN AND YOU ARE OUT OF BED HOW GLORIOUS THAT I, THE GREAT PAPYRUS, COULD BE THE FIRST TO SAY-"

Frisk waited hopefully hoping he'd mention her birthday holding in a breath.

"GOOD MORNING!" He smiled and continued analyzing the cereal box.

Ok… maybe only he forgot. Which was impossible because Papyrus loved birthday parties.

"Uh yeah, good morning…" Frisk spoke up a little craning her neck to see Undyne and Alphys looking at her from the corner of their eyes. They quickly looked away.

"Morning punk." Undyne smiled showing her sharp fangs out as she smiled though it seemed a bit forced.

"Morning Undyne. ...Alphys?" Frisk frowned slightly noticing the young scientist was awfully quiet this morning. At the mention of her name she jumped up and shook her head. "H-h-hi." Alphys gulped out and buried her nose into the manga.

Frisk raised an eyebrow stomping her foot a bit as she looked at Asgore expectantly. "Your newspaper is backwards." She snapped slightly crossing her arms over her chest.

He laughed nervously and corrected himself. "Oh, why yes. But isn't this how you youngsters like to read-"

"We don't read newspapers." Frisk sighed shaking her head hopelessly moving her gaze towards Toriel.

"Hi mom." She mumbled with a small smile.

"Oh hello my child. How are you?" Toriel greeted kindly. Her cheeks were rosy but otherwise she looked calm, too calm…

"Good." Frisk answered unsure looking at everyone.

"What is going on here? Don't you all know what day it is today?" Frisk inquired biting in her bottom lip.

"Of course we know the day!" Asgore laughed putting his newspaper down.

"IT IS INTERNATIONAL PIE DAY OF COURSE HUMAN!" Papyrus exclaimed happily.

Frisk gawked at everyone noticing the pie in the oven. They couldn't be serious… could they?

"So that pie there… in the oven, is it for me?" She asked Toriel hopefully changing the subject. The goat mother laughed a little and nodded.

"Why yes of course! It's for all of us!" She beamed and took it out of the oven laying it on the table. It smelled too good to be true.

"Oh." Frisk let her shoulders sink as she heard shuffling behind her and turned to see Sans standing there with a big grin, hands in his pockets.

"Sans!" She jumped in surprise looking at him expectantly.

"Kid… you look like someone rattled your bones or somethin'." He chuckled rather loudly and everyone else laughed though it was forced.

"I- Oh. That's all?" She rubbed her lips together nervously. They couldn't have forgotten, could they? There was a nagging voice at the back of her mind telling her to let them know but how could they have forgotten?

"Um, good mornin'?" He ruffled Frisk's hair and walked over to the kitchen table as Papyrus cut him a piece of pie. "OH MY GOD SANS. DID YOU KNOW IT WAS INTERNATIONAL PIE DAY?" His voice echoed through Frisk's ears and she tried not to feel sad. She then noticed Sans' attire and frowned. "W-why are you wearing Asgore's suit?" She pointed to his new clean, black tux. Sans laughed slightly. "I decided, why let a day like this go? I mean we aren't doing anything special so I might as well go be lazy somewhere else, ya know?"

"No I don't know. And I have never heard of Pie Day unless you mean the number because that was two months ago. Are you guys being serious?" Frisk stomped her foot slightly watching everyone with a frown.

"Well you should know, I mean you've lived here far longer than any of us." Undyne bellowed and Alphys let out another impatient squeal. Frisk paid no attention to any of them and just looked on trying not to let out a tear or two. Maybe they were just faking it, right?

"Aren't you going to sit and eat my child?" Toriel asked sweetly cutting out a piece of pie for the young girl who shook her head.

"No. You're right Undyne, I have lived here long enough to know what day it is." She declared and the smirk Sans gave her made her want to scream. It's as if he knew her discomfort and was just watching her to make her feel worse about it.

"And that is?" He asked casually, arms crossed over his chest as he leaned back and brought his legs back on the table despite Toriel's disapproving stare.

"That today is Thursday and I need to go get ready for school." She gave a decisive nod and then turned on her heel stomping away, loud enough so they could hear her anger.

Once she rounded a corner Frisk slammed the door and then silence.

It wasn't long enough until Alphys broke the silence as she let out a yelp: "FRISK WE'RE THROWING A SURPRISE PARTY FOR YOU." She then slumped in her seat and sighed in a satisfied way. "That was so hard, I swear I would have told her if she would have looked more hurt than she did." Alphys shook her head. Toriel nodded in understanding as she took her seat and eyed the pie. "I felt so bad watching her get hurt… my poor little child." She shook her head sadly.

"Guys come on, I know Frisk, she can do this." Sans smiled.

"She can stay determined." Asgore stated rather proudly.

The older skeleton rolled his eyes at the cheesy line and sat up. "And since we're all feeling blue, anyone want to hear a joke?" Everyone groaned and began rushing about to continue the morning.

Frisk rushed out the door without saying goodbye to anyone or giving Toriel a kiss goodbye. She wasn't necessarily angry at her friends, just disappointed.

"How could they have forgotten my birthday?" Frisk wondered aloud as a breeze blew by and golden flower petals blocked her view of the bus.

"I didn't forget Frisk." A soft voice made Frisk jump up in confusion as she looked around gripping her backpack close to her.

"Wh-who said that?" She asked nervously looking around. A couple kids walked past her and snickered making the usual comments that were supposed to bother her but never really did.

"It's me… your old friend…"

Memories of the encounter with the golden flower made Frisk's heart race in fear as she walked a bit faster. The bus had just pulled up on the curb and was loading the first couple of students.

"N-no… I- Y-you…" Fear was soon replaced with the realization that she was also talking to Asriel. Her heart softened and Frisk found herself slowing down.

"It's Flowey. I hope you haven't forgotten how you left me under here… all alone and scared." His voice ran in her head and she shook her head holding up her hands to her ears.

The bus was now closing its doors as Frisk stopped her walk all together.

"N-no. I swear, it wasn't like this at all. I didn't mean to do it, I never did it…" Her voice faltered and she sank to her knees as the bus' engine roared to life and sped off without her, leaving her alone with no sanity.

"Oh but you diddddd. You see I at least thought you would take pity on me and bring me up there with you… I had hopes that you'd teach me how to love again Frisk… But you never came back. YOU LEFT ME BEHIND." His voice began changing into a darker, more sinister tone that echoed in her mind.

"No! I wanted to but I couldn't! Please understand Asriel-"

"My. NaMe. iS. FlOWey!" His voice went back to being high-pitched and Frisk screamed as she felt her head behind clogged up in vines. Her vision blurred and she fell to her knees shaking her head and trying to outrun him, get him out of her head, but once he was gone she still felt his presence.

He had not just left a memory in her brain, but a hole in her heart she had so desperately worked on closing.

The vines were endless and seemed to lock up the young boy but his heart had been lost for so long he had forgotten how to love…
