Okay, not all Shoujos have silly characters, but Shounen/Adventure-Shoujos definently do, i.e. Mamotte! Lollipop or Fruits Basket, matter of fact, but I do really recommend Kamisama Hajimemashita for you to read, or the anime for you to watch. The anime's even more amusing because the male lead (Tomoe) has Sebastian's voice actor and the female lead (Nanami) has Happy's voice actor, both of which sound hilarious when they start shouting, because then they really sound like Black Butler/Fairy Tail.
