Kim Jongin escapes from the abominable Columbia University much without the knowledge of his parents and takes refuge in the home of his trusty childhood friend, Lim Shihyuk to escape everything. Everything was well, until Shihyuk’s younger sister announces that she was returning from Taiwan to her brother’s home. The last time Jongin had seen Lim Hayeon was when they were fifteen and not only was she extremely annoying, she was also fat and was very clingy especially around Jongin. Jongin actually hated her. He was not happy with the fact that she was returning and would be literally living with him, he wanted to get away. Well, that was until he realized that Lim Hayeon was not so ‘fat and clingy’ anymore.
