Donghae (the everyday normal guy at school) loves Eunhyuk or Hyukjae (the rich and popular kid) with all his heart. Though, Eunhyuk could care less about him. What happens when his sister, a sccientist who makes potions and medicine that can do impossible things, came and try to help? What is her idea? Sorry if it guys, it's my first fanfic ever written.
