Naughty Honey

Poor Yuzu is an orphan who's too clumsy to hold a job. She's reduced to living in a playground -- until a handsome stranger named Hassaku informs her that she's heir to a fortune, and whisks her into a world of wealth, power, and more hot suitors than she can shake a scepter at! But there's a catch: Hassaku must turn this klutz into a lady of refinement, or Yuzu will lose everything!

Also included in this manga is an extra story called Naughty Honey:
"The boyfriend I made in college cheated on me."

When she caught her boyfriend sleeping with another woman, Kayako Ueno broke his front teeth... and it will cost her a hundred-thousand yen to repair them. So she takes a part-time job as a home tutor-- for playboy Haru-kun.
