And she has a lot of enimes that are out to get her. Which is why she doesnt have any friends. And that's OK with her. Most of the other students at her school are scard of her and they know not to mess with her or else they will get their ass kicked. But there is a group of boys who aren't scard of her. And they go by the name Bangtan. Bangtan is Seoul High's hottest and badest group of boys. But they are no match to Tamo. Tamo has a thing for one of the members in Bangtan and its Jungkook.
