I was reading this kind of scifi fanfiction about EXO. But after searching hundreds and thousands of stories, can't find it. I forgot the title and I thought if I find manually I would recognize it. But still no hope.

At first the story tell about a girl that live in asylum because her parent thought she's crazy for injuring her back, which is not. One day a boy, Baekhyun came in. She captivated by his blue eyes, which strangely only her can see it.

After some time, she managed to find out that he's from another world and he's a guardian of that dimension. Later on, they become closer, and he told her that he felt magic radiated from her. Baekhyun couldn't go back to his dimension alone, because earth his magic out of his body. So he told her to go to his dimension and find his friends to seek help.

She went there and found suho, and meet the others. They went to this cave and go to the earth and bring baekhyun back. The last thing i remember about the story was she found out her injured back is caused by a magic resistance, like something want to come out. 

If anyone find it, can you tell me please?
