arite so i just saw oldboy which is a father/daughter relationship, and this raises a question (that is less extreme lol). let's say u have a long lost sister that u never ever met in your life, but while growing up say in school u fall madly in love with her and she does the same to u. then after a while, u find out her true identity, what will u do?
(if ur a girl, substitute sister with brother)
