You and Myungsoo are childhood friends and best friends. You both come from a wealthy family. You always liked him. He cares a lot about you too. After your college graduation, you were going to confess to him. However, before you had the chance to confess to him, you discovered something big; something that you would have never expect, something that put you in disbelief. To your surprise, MYUNGSOO IS GAY. Your heart was shattered into a infinite amount of pieces. What's worst is not long after you found out the one you love is gay, your parents and his parents already set an arranged marriage for the both of you. To marry someone you love is suppose to be one of the happiest thing in the world, but not for you. Your love is impossible. Not unless, you can change his ual preference. "It's decided. As his wife, I'm going to change him and lead him down the STRAIGHT path."
