What do I do now?? (Niam Mpreg)

Liam left. He packed up all his stuff, and left. Only trace of him is a letter addressed to Harry, Louis, Zayn, and his ex-boyfriend Niall. Nothing more is left of him. No one knows where he went. He just left. Have you heard the term "Disappeared from the face of the Earth?" Well, that's just what he did.
