"Hi, I'm Y/n! Boardcasting at my way home. It's so dark here, oh wait it already midnight! Teehee, I have such a golden fish brain. This is Alexandrite and Mary, Say Hi!"
You turn your camera phone to two girls in front of you. One with white hair and the other is black, the white hair waves at your camera while the other showing the middle finger. You smile and continue to introduce them
"As you can see, this white beautiful hair is Alexandrite. She such a angel right? The other is her sister, Mary. She not very positive haha, such a badass person right?"
You run on top of them, the camera show the three. Your f/c eyes sparkling like a star on the night sky, you smile excited. Alex is chuckles and then came to hug your back,Mary just sighed then came after Alex, she seem pretty annoyed but hugging you the same time. They acted like they are kissung your cheeks make you suprised blushing and then both three laughing. You stop recording and look at them
You: "Pfff, why did you two do thatttt! I'm embarrassed you know?"
Alex : "Oh my our little Y/n is embarrassing! Do you need any kiss to cool it down?"
You: "No! That not what I mean! I-"
Mary: "Need a french kiss on a lips"
You blushing hard then punch them both in the arm, they giggles. You three talking about many school and social media things, then Mary start to shout out a idea
Mary: "Do you know the Underground world? Where monsters live before? I heard that it up to the hill near our places, wanna search for it now?"
You: "Sound good! Many things that we don't know will reveal for us, your answer Alex?"
Alex: " I... Don't think is a good idea, I know this time monsters and human can live peacefully with each other but maybe they can be dangerous if we found one down there..."
Mary: "Oh come on! Stop being such a coward miss "Perfect", you scared that just a little accident will make your talent blow away idiot?"
You: "Mary! You shouldn't say that to your own sister! That's rude"
Alex: I-... Fine then"
After hearing Mary words, Alex seem down. You don't know what happened with those siblings, but just see that Mary really really hate her own sister. You comfort Alex and then walks to their house, why did you live in their house? Because you don't have a house, you have been abandoned by your owns parents, when you think it's no hope left. Alex appears and save you. You're thankful and still kinda shock when you know she is a lady living in a big mansion along with her sister. Mary quickly grab two helmet and throw it to you and Alex, she wearing one on her head and then start her racing motorcycle
Mary: "Hop in will ya? I'll ride you to paradise that can easy turn to a nightmare"
Alex: "Do you think it's a good idea? I suggest three of us should go to sleep, it's lat-"
Mary:"Then sleep on your own then, me and Y/n won't spend all night hearing your stupid advices!"
You: "Mary!"
Alex doesn't say anything get on the racing motorcycle with you, then Mary gave both a big spooky smile. Ready or not? She drives fast on the street, you are amazed by the beauty of the city along with the night. How many cars you passed and the electric light of each advertisement blink like a small club. You giggles, but Alex seem really down. Is she worried? She wants to say but then give up. Mary enjoying the wind blowing with her hair, lavender smell make you want to keep smelling her hair. At then end, she stop at the hill, it was dark and scary, but Mary have prepared. A flashlight for you
Mary:"Go with me will ya? If something dangerous call me. I'll protect you like a princess dear"
You: "I'm not a baby you know! I can go by myself haha"
Alex: "Y/n... I still suggest-"
Mary: "Well let's go then"
Mary seem annoyed and grab your hand in the wood, you can hear Alex shout behind "Wait for me". Actually you kinda nervous but Mary confident smile calm you down somehow. You feel proctected, warm and somehow relief. Then you heard something, it whispered in your ears "You are going the wrong moves Y/n" It freak you out a little and make you hold Mary hand tight. You said tht to Mary, she start to get on her guard, be sure that you are alright. But keep walking like this make you feel a little bored, so you begin to talk with Mary
You:"Hey, do you know Sans?
Mary:"You mean that stupid skeleton that on the news these day?"
You:"Mary don't be rude! I think he is really funny and attractive"
Mary:"Every girls say that, he is such a trash when just sleeping and tells stupid puns. I don't know why he became famous"
You: " Because he is intelligent,funny and mentality!"
Mary:"Yeah yeah whatever, I still hate him"
You pouts but then stop because that voice whispering in your ears "Help me!" "Who do you choose Y/n?" and then a lots of laughing in your ears, make you scared. You pursed your lips, bad feeling keep crawing for you back, then you decided to go back
You:"This is scary, I'm going back"
Mary:"Aww come on! The hole should be somewhere near here. We almost find it!"
You:"Nope! I'm leaving"
When you turn back and just started walking back, you feel. A big black hole and look like there was no end in this make you frightened. Luckily Mary catches you arm so you didn't completely fall into it. You can hear footsteps hurry running to both places. It was Alex, she frightened just like you and tried to get you up to land. But Mary really get annoyed when she came, so a weird idea come through her mind. She smirks then push her own sister in the hole. You see Alex drop down make you look up at Mary. Tears start leaking out your eyes, and then Mary drop your hands. Make you fall but she jump in the hole too. Hugging you tightly and make her back become your cushion. You closed both your eyes and keep thinking you will die
------------------------------------------
For a while, you are scared to dead but a hand pat your head. It was Alex, she worried. You start to cry and she hug you
Alex: "Don't scared, I'm here, I'm here"
You:"I...I thought you died! How did you manage to survive?"
Alex: "Silly there is a soft grass hold us"
You:"Ah...! I'm such a fool hehe. So where is Mary?"
Alex:"She said she is waiting for us after that cave"
She says pointing to the dark cave, then smiles relief. She holding your hand and you two walking in to it. You didn't think the Underground was so beautiful. It's just look so peaceful, make you smile warmly. But at the end of the cave isn't Mary. You recognize him, it's Sans! SANS THE SKELETON! You don't know how to react, completely in shock. Alex polite tap his back then ask Sans, but they like knowing esch other for so long. You kinda jealous
Alex: "Can you guide us to my sister"
Sans: "Sure sure, she is such a mean girl. Nice to meet you kid, I'm Sans - Sans the Skeleton"
You:"OMG, I-I saw you on newspapers and magazines!"
Sans:"Heh, maybe I'm so FANbulous"
You giggles and follow Sans through this strange place, Mary is waiting for you at the end. In front of a huge gate, Alex thank you Sans and is going to get you out of here when you heard a loud noise behind the gate. Sans is looking serious then told the three step back. But Mary doesn't care about him, open the door and you saw a group of 5-6 skeletons and especially they look like Sans. But they look creepy, you stand with Alex behind the real Sans.
???:"Heh, what is human doing down here?"
???:"I don't know but just kill them should we?"
???:"One head dog coming up"
???: "JuSt @nOt11Er Gl1tc11"
A skeleton hold a axe with some red liquid on it, seem like blood and swing the axe at Mary's neck. But she fast enough to dodge it, a sharp knife slowly slice down in to her hand. She stab it in the skeleton shoulder make him back off, she giggles to how weak he is but then she take it back. She has forgotten that there are like 5 of them, they are trying to kill her. As soon as she keep dodging all the attack she feel exhausted. Sans still helping her but when he want to move her away from them, the black with many tentacles one grab her them go in a portal with the other. She struggles, even hitting them hard but somehow it doesn't work
Mary:"WHAT ARE YOU DOING? LET ME GO! Y/N! SIS! DOING SOMETHING"
You:"MARY! I'M COMING FOR YOU"
       When you just going to save her, Alex hold you back. You stared at her, completely confused. Why did she hold you back, her sister is in dangerous. You still struggle out to save Alex, the snow make you feel cold, but the scene in front of make you panic. You can't do anything, Alex and Sans don't let you save her. In the end, you just see Mary eyes wide, begging you to help then disappear after the portal. You holding your head, shaking your body because you let your best friend being kidnapped by the bad guys. You feel shame, pity and last but not least angry. Alex hand place on your shoulder but you quickly slap it away. Anger fills your eyes, your heart and you brain. You pinned Alex down, tried to choke her as hard as you can. Tears begin run down your cheeks
You:"WHY DID YOU HOLD ME BACK ALEX"
Alex: "Y/n...I..*cough*"
You:"SHE IS YOUR SISTER, YOUR SIBLING"
          You choke harder, wanting her to die but Sans use magic to move you away from Alex. You shouting, struggling and wanting to kill the fucking one who let bad guys kidnapped her own sister. Alex looks depressed, she coughs then look at you
Alex:"Y/n...I'm sorry! I-I just don't think is a good idea to let you help her"
You:"SHE IS YOUR OWN FUCKING SISTER, WHY DIDN'T YOU SAVE HER"
Sans:"Woah, chill kid. You could be dead if you save her. Don't cha think? They are too strong, even I can't do anything. We'll save her later, okay?"
You:"But..."
Alex:"Y/n listen to him please, I did that because I don't want to lose anyone anymore. Please...listen"
       You sighed, then nodded your head. Sans let you down, the chilly weather make you feel cold. You look where Mary has been taken, "I will save you Mary". You think like that then go back to Sans and Alex. You don't forget to give Alex a dath glare too
You:"I'm exhausted, can we just go somewhere to rest?"
Sans:"I know a place kid, why don't you go to my HORSE?"
      You giggles then look back at Alex, smiles like a forgive word then followed Sans to his house. Maybe your journey sarting from now on, wonder many dangers you will get?
