Always a great one-shot to come back to! Light and sweet :3
yeah, Kurogane-sensei is in my top 10 list. his works always tend to be fun and cheerful. actually, I don't think I've ever read a sad or depressing Kurogane Ken story. does one exist?
Really?
Inter Face???
Hoshikawa Ginza District 4 with all of its angst for the future and drama?
My Path was pretty dark and depressing?
Granted, Persona Karen came out after you posted that comment, but there you go, darkness.
Heck, even Shoujo Sect had its fair share of drama/sadness.
Alright, not all of these are necessarly "sad and depressing" or end that way, but they are definitely not "fun and cheerful".
So yeah, they exist. Have fun.
