Zhang Ailee,  a twenty five years old junior editor in one of the famous korea magazine just broke up with her 2 years long boyfriend five hours ago. She is devastated because she thought he is the one. Not until when she caught him was kissing with one of her officemates. 

She has no where to go since she has lived together with his boyfriend after they had been together for two months. All the people around them keep saying they are moving things too fast but at that time, they are just two person madly in love. 

Where should I go now? Oh right, Minseok oppa!

 Just when she wants to rings her close friend which she already thought as her own older brother, Kim Minseok, her phone rings and looking at the unfamiliar phone number, she raised an eyebrow but still answer the phone. 

“I understand. I will go to China tonight.”

Taking off her pearl necklace that her boyfriend -ex boyfriend bought for their first anniversary before on the coffee table beside her small note. 

“I saw you with Hana.”

There’s no need to say anything more. They already had a few fights before regarding this matter since she had caught him talking intimately with her during their nights out at the bar but he of course denied they have something going on. She is glad she saw them and the phone call just now will be her reason to leave Seoul for a while. 

She also send her company an official email stating that she needs to take three months emergency leave starting tomorrow. 

Ailee admits, going back to her birth country is not her first choice however the person she really want to see the most is there so she must go back. She demands an answer from him on why he never try to search for her during all this fifteen years.
