Nothing. I think you mis-heard the phrase Queen of Hearts, which is slang for a woman who has a lot of romance.
or
In victorian times the term "to be clean of heart" was occasionally used to mean "to be honest/innocent" similar to the more used phrase, "to be pure of heart" meaning the same. However, given your phrasiology in the question it might be that the first answer is closer to your required resolution.
dont you mean kingdom hearts with the kid named sora ok its called Simple and Clean second game Sanctuary
Simple and Clean
Which one cause kingdom hearts 1 is simple and clean, and kingdom hearts 2 is Passion/ Sanctuary
That would be Utada Hikaru. She is the singer of the Kingdom Hearts theme songs. (Simple and Clean/Sanctuary)
The Kingdom Hearts 1 theme song is "Simple and Clean" and the Kingdom Hearts 2 theme song is "Sanctuary" (aka "Hikari" for Simple and Clean and "Passion" for Sanctuary). They keep those songs throughout the series.

Simple and clean.
Utada Hikaru
well T.P. with our hearts and hands
Its tells of the past of previous Keyblade wielders. There is a short scene of a brawl better then "Keyblade Masters" that results in Kingdom Hearts being produced and Mickey showing up to potentially clean things up.
Simply give your duck a lot of affection until you have the hearts of affection enough to win the festival, the more hearts you have more chances of winning, these hearts you get them, preferably using gloves petting, eating well and clean (the truth is that I do not remember if you can clean) then try and after several days and will have many hearts.
The song used in the first Kingdom Hearts is 'simple and clean' by Utada Hikaru. The song used in Kingdom Hearts II is 'Sanctuary' by Utada Hikaru.
