まんきつ！～コミックカフェへようこそ！～

The game is about running a manga café named "Orange Chiffon".
Your childhood friend's father went out for a long trip and left his only daughter, Yuu, as the manager substitute.
But because Yuu isn't good at managing the café, plus there aren't much customers coming to the café, you were asked by his father to help run the cafe instead.
Your goal in this game is make the manga café prosper.
