Lets catch myself up in the questions:
Soul Charge: Will most likely be hit to 1 because its almost as bad as rekindling but not entirely not that unbalanced, I mean you do need to pay X000 depending on the summons and you can't attack the turn you do it. Plus you can easily walk into a Torrential or a Bottomless which then throws off the entire play.
Please A Woman: You don't....
Anyway, depending on if your trying to please her by flirting or please her by being a good boyfriend/girlfriend.
Usually the way I please them is by talking when they want to talk, flirt when they want to flirt and keep them relatively in a good mood and then if their upset, do something you know will make her happy, like one time when my friend broke up with her boyfriend of 4 years I bought her ice cream and soda and walked to her house and we played board games, she ate ice cream and we enjoyed the day since then anytime she's feeling down I tell her one word and I'm off to get Ice Cream and she immediately brightens up.
So to make a short story short, just be you, don't force anything, and be friendly, you'll either get friendzoned (which isn't ALWAYS bad) or you and her will develop a powerful relationship.
