There are many rules to follow if you're a heart breaker; have fun, don't get attached, keep your heart open enough to swindle people, and look good enough to make a statue turn their head. But if you're Sasuke Uchiha, the main rule to not break is 'don't fall in love with the cute blond your friend introduces to you', despite how hard it is. Too bad even being straight couldn't keep that rule unbroken.
