Lying Child | Ban X Elf!Reader

(Y/n) has known Ban since he was a mortal. They weren't necessarily immortal, but they had a very long lifespan like fairies and giants. Even longer than that. They had known him before he even knew about Elaine and that cup of stupid, stupid, water. And she's been with him. Since as long as she can remember. But she disappeared, since she did have the responsibility of being the Queen of Elves. And she was gone when Ban found Elaine. And when Ban told her, she was completely heartbroken. She went back to the Elf Kingdom and hasn't seen Ban since. She knows all the other Sins closely, and are their friends. But she's not sure if Ban is still her friend.
