just be yourself, it's better in the long run. while there are spell that can make a person 'love' you, it's a hollow love. the spell you cast takes away this persons free will so they're doing what you want, not what they want, so they don't really love you. also, there free will shall fight against the spell, so they will break free of the spell, maybe in a day, maybe in 10 years, so you'll need to constantly re-cast. do you want that?
other options you could try is casting spells over yourself, like using potions for clear skin and healthy hair. final option, use the science of smell to get a girl to fall for you. still not the best choice morally, but it's another option. just meditate and think about it before you cast on another, be careful what you wish for after all.
