So wheres what I think happens; Lucy is reading over her book she's going to give to Levy. Natsu comes and and is like 'OH MY GODS IM SOOO BORED' And notices Lucys book. Natsu grabs the book and startings reading it, much to Lucys embarrassment. (And then Natsu realises the book is... Romance?) Lucy tries to leave, only getting stopped by Natsu, and pulls Lucy into a kiss. And then Natsu pushes Lucy forward, causing them to fall underneath the table... (Im not going to say any more about that, so moving on...) and then Lucy gives the book to Levy, thinking about what happened when she was reading the book over.
