in this school potion making was one of the classes, but it wasn't really potions, it was just using normal science tools, liquids and such to make new kinds of usable liquids,what they call "potions". you were seated with your best friend and your room mate, han jisung behind you and his best friend next to him, the task was to make what the teacher said to be a love potion, but he told you guys it wouldn't work so that you guys wouldn't have ideas to use it on anyone, however you bumped into jisung while wanting to go and show the teacher the product, and your "love potion" spilled, on both of you, for you, the one eighth of the liquid ended up on your lips which you accidentally swallowed down, and the potion actually worked, so your teacher kind of lied and you fell in love with him. you two were on the ground, the pink liquid on your clothes, and some on his, you were kinda dazed, everything was spinning and so was your stomach.
