She's an outcast, getting bullied and said that everyone who get closer to her or be friend with her will also get cursed so no one dare to get close to her. 2 girl also bullying her, a popular one. And a guy who look like a thug. Those three know she can't really see a ghost but they still spread rumors for it. Saying it for 'fun'. One day, to hide from those three. Eunha Joo goes to the nearby school, abondon place where students can't go. But unfortunately those three students who bullying Eunha Joo found her. They saw a book of ritual and used the blood of her to summon someone. They lock her there so she can see if it work. Leaving her alone there and you those three left. You got summon at first you look like a creepy creatures, you ask her why did she summon you and she said that she was bullied. You said something like we're the same, I can smell it on you, the loneliness. You then made a deal, do the ritual again and you will help.
