YAY ! That is one awesome idea to do the Part II of the Runouw Series (Part I is TRE). So yeah, that gives me an idea ! Only one, but a brilliant one.
Because once you'll have finished that, I'll continue the series, YEP ! I have already Part III in mind, the olny thing I need is to someone to disappears and doesn't come back even at the end of the story. It would be better if it is someone important, or even ME (could be cool)! If it doesn't bother you. Just put that anywhere in the story. Anyone (even me or you, just know that the one that'll disappears will be very important in the story), anytime.
Anyway, keep going with your wasom story
