One of the few mangas that ever made me legit emotional. If you're looking something character and story driven with a good mix of drama and comedy, then you don't have to look any further than this. There's no sex in this, I'll say that straight off the bat, but I fell in love with the characters (not just Takara and Kiyomine) and I couldn't tell you how many times I've come back to re-read this.
Komatta Toki Ni Wa Hoshi Ni Kike!
