Dear Darlin, 

Please excuse my writing, 

I can't stop my hands from shaking, 'cause I'm cold and alone tonight

I miss you and nothing hurts like no you,

and no one understand what we went through.

It was short. It was sweet. We tried.

We tried.

Postcards. Love. Betrayal. Trust. These things revolved around Choi Sooyoung, always hurting her in the end and letting herself get broken all over again. She wanted a new fresh start of her life, she wanted to be a new her again. But everything went wrong when the complications of sibling rivalry and love started to kick in her life once again. Stuck in between the love of her life, her sister, and someone that really cares for her. She must chose one, but will she? Or will she just let everything goes? All she wanted was to smile genuinely without having anything to be troubled with. All she wanted was someone to love her.

Choi Sooyoung felt like everything was broken, when Yuna had faked rumors about Sooyoung aborting her own child. And the surprising part was that, everyone believed those rumors without any evidences and began to steer themselves away from Choi Sooyoung. Just like that, she lost the love of her life, her dignity, and her once best friends. She gained nothing until one day, she got closer to Kim Myungsoo, the heart-throb and a cold jerk plus a stranger who had been sending her postcards  of encouragements.

And when he came back, he used his parents forcing him away to overseas. Was he telling the truth? And luckily for him, Choi Sooyoung was still in love with this handsome idiot. But things started to go wrong during one point of a time, when Kim Jongin had no choice but to hurt Sooyoung.  Jongin is definitely not someone that someone would want to mess up with. Will he give up everything inculding his pride, wealth, and dignity just to be with Sooyoung?

Choi Yuna ;

When you look at her, you might actually thinks that she is a kind and angel-like. Well, she is an angel to everyone else but not her sister.  

Although Sooyoung and Yuna were just half-sisters, but Yuna hated it whenever Sooyoung grabbed everyone's attention since young. Yuna changed herself, so that she would be much cuter, prettier, and ier than her sister so that everyone's eyes would be on her.

Yuna just loved attentions that she gained because of her beauty. But no matter how hard she tried, Kim Jongin, the man that she loved wouldn't ever look at her in the same ways as other guys do and unfortunately it was because he was her sister's boyfriend. She tried all the ways to mark him as hers, and only hers.

 And she succeded, but when she learnt that Jongin still loved her big sister, Yuna swore to herself that her beloved sister would never ever enjoy her life as she used to be. Yuna would make sure that everything of Sooyoung's would be snatched away by her, and Sooyoung would be broken so much that nobody could save her. Yuna, she is a girl who didn't know about love or how to love correctly.
