Summary: You and Yui were working in Chemistry Class for a Love potion project. However, things start to get weird after your brothers get exposed to the love potion.... otherwise known as the Love Poison. Sorry, I'm late, been busy with school. Also, this chapter is not part of the story.

F/F = Your Favorite Food

In Chemistry Class, You and Yui were dressed up in white coats with gloves that matched your outfits. Your Chemistry Teacher, Ms. Hearthstone, said " Okay, Class. As you already know, today is Valentine's Day." She grabbed some chalk and wrote on the board ' Love Potion Project' Ms. Hearthstone spoke " Which means that today, we're going to be creating a love potion." She continued " Everyone grab your Chemistry textbooks and pick your partners." You and Yui turned to each other, knowing you two were going to be partners.

You and Yui gathered all the ingredients and placed them on the table. You placed the candles under the mini cauldron and lit them up. You turn to the chemistry textbook and read " Now pour some water." Yui brought in a cup of water and pour it into the cauldron. Yui turns the next page and reads " Now, chop off the rose's petals, bay leaves, and lavendulan's petals." Both of you cut the petals and leaves and carefully added in the mini cauldron. You turn to the next page " Now, stir the ingredients while reciting the spell." You grabbed a spoon and stirred the potion. Yui cleared her throat as she read the spell " From the heavens above, let this flame of passion burn within my lover's heart. The moment our eyes meet, may we forever be tied to the strings of love." After the spell was recited, the potion had transformed from pink to dark red. You gasped " Yui look. We did it!" Yui looked at the potion and smiled " Amazing!" You said, " Let's take this home and show it with my brothers. I bet they'll be impressed." You grabbed a glass jar and scooped the potion. You place the lid on top and tighten it.

* Another Time Skip (Brought to by Yui's roses. Bring a smile to everyone's faces.... or get bitten by a sadist vampire)

You were carrying the love potion to the living room, you placed it on the table " I'm just going to get a quick snack before I do my homework." You walked away from the dining room. Ayato marches in, he grunted " I can't believe that Table-ware Otaku is making me brew tea for everyone. It was just a little prank." Ayato notices a glass jar that contained pink liquid. He walks up to the glass jar and picks it up. Ayato squinted his eyes at the glass jar " What is this?" He placed a finger under his chin " What if I used this as a replaced? That way, Reiji would let me off the hook and he'll never know." Ayato chuckles to himself and walks away " Ah, Ore-sama is too good." You returned to the dining room with a plate of F/F. You noticed your love potion was missing from the table. You dropped your snack and ran towards the table. You said " What? Where did it go?" You searched the living room but, found no sign of the love potion. You ran upstairs to Yui's room and knocked on her door. Yui opens the door " What's going on, Y/N?" You shouted " The love potion! It's missing." Yui's eyes widen " What?! Where did you put it?" You replied, " I put it in the living room for a moment but, when I came back it was missing." Suddenly, a loud shattered made you both jumped. Yui gasped " What was that?"  You turn to Yui " That came from downstairs" You and Yui ran down the stairs and into the dining room. As you turned your eyes to the scene, you let out a loud scream. You saw your brothers on the floor laying on the floor.

 You ran up to Ayato and shook him " Ayato! Wake up!" He didn't respond, you started to cry " P-Please....open your eyes. Why aren't you opening them?" You heard Yui spoke " Y/N, look over here" You turned your head to see Yui holding an empty glass jar. Yui asked, " Isn't that the jar that you put the love potion in?" You softly spoken " Y-Yes, but what happened to the potion?" You heard a voice grunted; You looked at your red-haired brother " Ayato?" Ayato rubbed his eyes " What's going on?" He lifted his head up and saw you, you noticed that his pupils had expanded. You smiled " Ayato! I'm so happy you're alive" Ayato spoke in an eerily tone " Melons, when did you looked so tasty?" After his first words, your body shivered " W-what?" Suddenly, Ayato pounced on you and pinned both your wrist to the ground. Yui screamed " Ayato! Leave her alone!" Ayato shouted back " Shut up, Pancakes. Don't talk to me when I'm having my dinner." He turned to you with a hungry look, Ayato said before revealing his fangs " You're so beautiful. Ore-sama wants to savory every last bite from you" You cried as Ayato moved his face towards yours " Yui, help me." Yui ran towards Ayato and pulls him away from you. Ayato growled at her as he tried to escape " Baka, get the heck off me." You quickly got up and backed away from Ayato. You asked " Ayato, what's wrong with you?"

Everyone heard a voice shouted " Hey! Get away from her." You, Ayato, and Yui turned to see Reiji awake. You ran up to Reiji " Reiji, something's wrong with Ayato." Reiji scoff " Unbelievable behavior, Ayato." Ayato glared at him, Reiji grabs your wrist and pulls you close " You know you shouldn't be touching my Y/N." You noticed Reiji's pupils were big like Ayato's. You spoke " Reiji?!" Ayato shouted " Baka, she's ore-sama's property" You struggle to escape Reiji's grasp " Let me go! Why are you doing this?!" Suddenly, you felt someone pulling you away from Reiji and landed your face into their chest. You heard them said " You guys are so loud, you ruin my sleep." You recognized the voice; you lifted your head to see your lazy older brother " Shu?" Ayato tries to attack Shu but, was held back by Yui " Why you little...." Reiji growl before speaking " Shu..."

You said " Shu? Something's wrong with Ayato and Reiji. I think they must have drunk the love potion" Shu death glaring at his obsessed brothers, Reiji and Ayato. He spoke to you " It's not safe to be here. Come with me" Shu picks you up bride style and teleported you both to his bedroom. Shu asked " Are you alright? Did they hurt you?" You replied as Shu placed you down " No, I'm alright. Thank you for helping me" Shu raised an eyebrow " Helping you? I wasn't helping you" You hum in response, Shu said " I didn't want Reiji taking my meal." You were scared " M-Meal..." Shu was slowly walking towards you, you backed away until you hit the bed. Shu pushes you to the bed, pinning your wrists above your head. You cried " Shu! Stop, let me go!" Shu revealed his fangs " Don't worry, it won't take long. Just stay still" You felt his heated breath on your face, you whimpered " Shu..." You noticed his pupils had grown the same size as Ayato's and Reiji's. In quick thinking, you kick Shu's groin. Shu lets go of you as he cried in pain. You got out of Shu's bed and ran out the door. You heard Shu screaming " Y/N!" You ignore his call and ran down the hallway. You went into a random room and closed the door. 

It was dark, you were breathing heavily. You thought ' Okay, I'm safe. It's just me in this dark room' Suddenly, you felt something wet touch the side of your neck. You flinched ' What was that?!' You heard a flirty voice chuckled " Kitten-chan~" Your whole body froze; you saw two green eyes glowing besides you. You screamed and ran out of the closet. You went into the kitchen; you hid behind a kitchen cabinet and heard footsteps approaching. You tried to maintain your breathing; you heard a voice chuckle evilly " Teddy~ Do you think Y/N is hiding here?" You thought ' Kanato? Oh no, not him too.' Kanato said " Y/N, come on out. I know you can hear me" You heard one of the drawers open, Kanato spoke evilly " Don't be afraid, I just want to play~" You peaked out from your hiding spot and saw Kanato holding a silver fork. You felt your face becoming pale, you hid back in your hiding spot. You started to tear up ' Oh my god, why does Kanato have a fork?' You saw a shadow hovering over you, you felt your heart stopped. Kanato chuckle evilly " Found you~" You slowly turned around to see Kanato moving the fork towards you. You were stabbed on the shoulder; you screamed in pain. You held your bleeding shoulder as you got up and ran off. 

You ran up the stairs " Yui! Where are you?" You found Yui standing in the middle of hallway. You ran up to her " Yui, there you are" Yui turns to you, and she smiled " Y/N!" Yui noticed your bleeding shoulder and covered her mouth in shock " Oh my, what happen to you?" You spoke " There's no time to explain, we've got to get out of here" Suddenly, a silver knife flies between both of you and lands on the wall. You heard a voice growl " Get the heck away from my Y/N." You both turned to see Subaru approaching from the dark hallway. Without hesitation, Yui grabs your wrist and drags you away. You heard Subaru running after you guys, Subaru shouted " Get over here!" You and Yui ran into your room. Yui shut the door and locked it. You heard Subaru banging on the door " Open this door!" You and Yui backed away from the door. You said, " What are we going to do? We got to fix my brothers before they kill me" Yui gets an idea, she gasps " I got it. I know how to fix this" Yui looks around " Do you have your Chemistry Textbook?" You replied " Yeah, it's in my backpack. It's underneath my bed" Yui searches underneath your bed. 

You heard the door banged loud; you heard a flirty voice " Y/N~, We know you're in there." A soft voice spoke " Teddy and I are sorry for hurting you. Please let us in, we have a surprise for you~." You obviously didn't believe in their words, you shouted " Hurry up, Yui." Yui grabs your backpack and grabs out your Chemistry Textbook. She opens the book " I found it! There's an antidote." You heard the door cracking; you heard a rough voice said " Oi! We're starving. Let us in!" Yui reads the textbook " If you wish to reverse the effects of the love potion, reread the following chant aloud" You heard the door shaking aggressively, you screamed " They're almost here!" Yui shouted, " From the heavens above, I break the bonds of my admirers and burn these strings of fate." A hand punches through the door, you heard various of voices speaking " Y/N~" You felt your body shaking in fear " Oh no..." The hand unlocks the door, you saw the door slowly open revealing six of your obsessed sadists brothers. They all ran towards you as you backed against the wall. Yui shouted from the top of her lungs " Free thy souls from this spell and return them back to their place" Finally, the Sakamaki brothers froze in place. You noticed that their pupils had shrank back to their original size. 

The Sadist Vampires looked at each other confused, Ayato asked " Oi, what's going on? What are we doing in Y/N's room?" Reiji sigh " If I were to guess, I say this had something to do with a potion" Kanato questioned " A potion? What kind?" You awkwardly rub the back of your neck " Umm...you guys might have to sit down for this" After several hours of explanation, Ayato spoke " Well that explains a lot" Laito chuckled " I knew you two had something to do with this" Yui said " Actually, we figure one of you guys stolen the potion since we lost it at the start" Reiji thought out loud " Hmm...the last thing I remember was punishing Ayato" Ayato looks away and whistles. Reiji turns to Ayato, and death glares him " Ayato!" Ayato nervously chuckles before running away. Reiji chases after him " Get back here!!!!"
