Kim Hyun A was Do Kyung Soo very first friend ever. He had never talked to anyone in his life; not included the times he talked about important things. They’ve known each other for three months since the Sport Day was held in their school. To his opinion, Hyun A must have been watching him a lot before as she told him that she felt sorry to see him being a loner.

 Giving away his bad thoughts not to befriend with anyone especially when that person is a she; because for him everyone in this world is a two-faced face, Kyung Soo instead agreed to create a new and first-time friendship with the girl that was mentioned earlier.

 Time by time passed, and Kyung Soo seemed to already know almost everything about Hyun A. However, all Hyun A had story-tell him was most about his great boyfriend named Kim Jong In and the least ‘bout herself; what she liked and disliked . She told him that their love had anything that showed the true meaning of beauty of love and was full of romance. Well, contrast to what Kyung Soo thought about their relationship, their love seemed peril when Hyun A mentioned him that they had made love almost every time they were out for date.

 Because of being Kyung Soo friend, Hyun A was involved in the mockeries that people threw towards him everyday. By such thing, Kyung Soo did not dare to give any uncomfortable compliment about Jong In and her as an appreciation of her willingness to befriend with him.

Not until the day Kyung Soo was visited by a crying-mess Hyun A to his shared-house with his aunty, he was infuriated with the news that Jong In cheated on his best friend. Days after that, Kyung Soo wanted to pay back for what he did to her. He had planned everything and all he needed was cooperation from the girls.

             “What is your plan Kyung Soo?” Hyun A asked and she got a frowned face; frown that signified wonder and worry simultaneously.

                 “I plan to pay back and make him experience the worst thing in his life...” Kyung Soo told and a satisfied smirk created on his face.

                 “How...?” another question asked by Tiffany, Hyun A’s closest cousin.

               “Tell you what? What is the best way for me to make that bastard to experience the worst and incurable heartbreak ever?”

  There, Kyung Soo went smirking again. Now, it turned into something look devilish and somehow he thanked God for creating him with such adorable, ‘innocent’ face.

“I’m gonna disguise myself as the most lovable girl ever and let him serve it...”
