Kawaii! I agree with shole, i think rin is the more daring one...just look at the PV of Len's "World is Mine". Anyway, I loved your story! Writer's Inability? I'm sorry, but I don't believe that. You're story's awesome! How could you say you don't have an ability in writing? Hehe...great job! I look forward to more great stories! (not to pressure you or anything...hehe)
