(A/N some events in the story will NOT be the same as the game.)

"Hey... (Y/n)? Can we go to Mt. Ebott now?" Your younger sister asked you. "Okay, okay Caitlin. Let me grab some stuff before we head out." you say, walking to the room you and Caitlin share. You take a suitcase and pack a few clothes for you and your sister, some snacks, some books, a brush, some of Caitlin's toys, a first aid kit, and some juice. You put your phone and earbuds in your pocket. You grab you and Caitlin's jackets, and call to your mom who was in the kitchen, "Hey, mom? Me and Caitlin are going to Mt. Ebott. I'll call you if we get stuck there." Your mom looks at you and nods, throwing you the house keys.
**a LA magical time skip**
"Oh my gosh... Thank you (Y/N)!" Caitlin yells, giving you a big hug and makes you trip on a vine on the ground. She tries to grab you, but falls in the hole in the mountain also. "HELP!!!!!" Caitlin screams.
*time skip once again*
"Howdy.. I'm Flowey... Flowey the Flower." You hear. The sudden noise makes you and Caitlin stumble backwards. "You two are new here... Arent'cha? It's okay." The flower says. "(Y/n)... I'm scared." Caitlin says. You nod and walk over to him. At least you think it's a him. "You want to leave dont'cha? Sadly, the only way to get out is blocked. But I can help you get there. Grab these 'friendliness pellets' and get some LV you know what LV stands for, right? Love. Grab as many as you can" the flower says. Not fully trusting him, you dodge them. "Hey, buddy, you missed them. Let's try again shall we?" 'He seemed pretty irritated I didn't grab them. Maybe I should try and grab one' you think. He sends more out, and you reach out to grab one. When you touch one, it feels like your hand got set on fire. "What the F-" you say before clapping your hand over your mouth, remembering your sister is right behind you. "Are you okay, (Y/N)?" Caitlin asked. You nod and you hear him say, "You IDIOT, in this world, it's kill or BE killed." His face turns demonic and he laughs, sending a ring of the 'friendliness pellets' towards you and your sister. They speed towards you and just before they hit you, they disappear. "What a horrible creature, torturing such a poor innocent youth. Oh, there are two of you. I am Toriel. Caretaker of the ruins. Follow me."

A/N: Like I said, most events aren't EXACTLY like the game, but it aligns somewhat with the game. Thanks for reading and there is more to come!!!
