Oh Areum, her boyfriend, Xi Luhan and her bestfriend, Choi Semi are known as the best trio in the neighbourhood and school. They grew up together. They did almost everything together. They stuck together like glue. Everyone thought separating them is impossible. Areum's life was perfect, she thought. Until one day, when her boyfriend asked her to break up. Her bestfriend started ignoring her. Then she realised how wrong she was. Her whole world came crashing down. 

What could be the reason? What made this trio that everyone thought was 'impossible to break' fall apart?

Will she be able to overcome this?
