You grew up together with Lewis, and you went through the same things he did. You were in the same orphanage with him, in the same abusive family, and you were also with him when he entered the portal as a child, when he was transported to the demon world. You two were never apart. Others might see your relationship as a strong one, like that of brother and sister, but it was so much more than that...

From the beginning, you didn't consider Lewis as your brother, and neither did he. You were friends at first, but now it was more than just siblings or friendship.. It was much more than that, but only the two of you knew about it.
