I'm the same way. You're more together than me. If I wrote more than one story at a time, my mind would be a scattered mess. If the words appeared in your head, that's a real spark of inspiration.
That's great! Warning though: From my experience, if people love one of your stories, don't stop writing other things. I didn't and I got stuck in a successful plot that sometimes I hate. I don't know if that's the case with you, but you never know.
I'm glad. It's hard to find stories on here sometimes that don't have the same plot and characterization. You're doing great. Read the second chapter, love it.
I just read your other story too btw xD I like it =D
