Flowey

Authors POV
The back of your head starts aching as you stand up and let out a small groan. You felt a sharp pain as you touch the top of you forehead only to see red dripping from your head. You see a glimpse of light as you look up to have noticed that you have fallen down into a really deep hole."How tf did I not see this gigantic hole while I was walking!! I must be blind and clumsy!"
You forget about it and start to move forward only to bump into a small an torn up flower. You try to ignore it as you start to walk away until you heard someone behind you sneeze as you quickly turn around "wh-who's there!!" You shout out quivering in fear." Please don't hurt me! I-I mean no harm I swear!!" You look down too the flower just staring at it with a blank expression as he does the same...

"AHHHHHHHHHHH OMGGGGG ITS A MOTHER FU*KING FLOWERRRR!!!!! AND HE TALKS!!!!!!" You scream out in fear."SHHHHHHHHHH!! She will hear you and your gonna get us both caught, and believe me, you don't want that!" The flower whispers loudly as you cover your mouth.
"Sorry." You quietly whisper to him. " It's ok, you didn't know since I can tell your new Around here." The flower said, "Yeahhhh I kinda just fell from that gigantic,obvious hole over there." You embarrassingly said. "Yeahhh, Well you weren't the first and you probably won't be the last!" The flower said. "Soooo..... what is your name??" You ask the flower. " My name is flowey,flowey the flower!! And your name is?" The flower  asked. "My name is (Y/N)!!" You proudly tell flowey. "But ummm.... flowey?? Who is she?" You ask flowey. "She goes by Toriel, caretaker of the ruins, she became completely insane when her and her husband split." Flowey explained. "Wow I feel so bad for her." You said. "Well don't, she doesn't deserve such pity." Flowey said back in response. "Well I should be going now." You tell flower as you pick yourself up and start heading towards the door. "Wait!!" You hear the flower shout. "What is it??" You ask the flustered little flower. "I-if  you don't m-mind, I would like too go with you.... to keep you company and safe!!" You stare at the flower . "Of course!!" You enthusiastically tell Flowey.
