Just a fanfic from Dgm, it's on my deviantart page aswell

"Twins?!?!" You nod. Everyone's shocked to hear when you say your Allen Walkers Fraternal twin. Lavi's shocked but like that'll stop him from being flirty. Lavi's a Bookman and divides himself between Exorcist and Bookman. He follows both but when a new exorcist meets him, what'll he do?? She's amazing and perfect in his eyes. But Bookman. Can't. Love. ....right? Credit to editor for the cover D.Gray-Man is not mine and nor are the characters Only character that is not from D.Gray-Man is reader but Lavi owns you ;) enjoy

When he thinks that you are asleep he allows his sweeter side to come out.
