Just happened to stumble across and read Kuroi Romance... I really enjoyed it!
Honestly, I wasn't expecting much (fanfics usually aren't all that great), but you're an excellent writer. I really enjoyed reading the story. If you're actually 15 (says that on your profile) then that's extremely impressive, especially your grammar. I write reviews professionally and I write fiction in my own time, but your grammar is way better than mine! Heh.
