Perfect Match

I am the one with the charming appearance, and you are the dark and cold heart. I am a chess piece that you play with at will, and you are the ladder to my glory and wealth. Even though I am just a lowly person, I can still turn the clouds around. Because there is an open fight, there is a secret fight, and I can't help it. Time flies by, and I just want to ask: Have I ever entered your heart?
