The biggest player in SM University had fallen for an ordinary girl, Im Yoona. But, Im Yoona was not really his type because she was just a poor girl. Her parents died when she's still young. She's living with her best friend, Taeyeon. She already loved Donghae for 3 years, only Donghae didn't realize it. Donghae always tried to grab her attention but failed until one day, he made an anouncement in school, saying that he loved Yoona. Yoona felt so happy that she accepted him as her boyfriend and they became a lovely college couple.

2 years later, they graduate. Donghae worked in his dad company and Yoona worked at Taeyeon's restaurant. Their relationship went well these 2 years but...

'I hate being trapped in between this two beautiful girl. The two girls that have stolen my heart.. Who should I choose?'

'Oppa.. I have a secret.. A secret that I can't tell you when I'm still exists in this world.. You will know it later.. Later.. When I already dissapeared from this world..'
