Choi Junhong was the kind of kid that had no friends, he only distanced himself for their own good but that just led to him falling deeply in love because nobody else was by his side. 

Jung Ahreum was the only one who wasn't afraid of the circumstances. She didn't have the heart to let someone live without anyone by their side because she knew what it was like. Living without a family, she believed that she knew well enough.

After what happened she closed off her heart to loving anyone but just when she had opened up once more, she was hurt again.

Now she knows that holding back, living in denial, stopping herself from the feelings her heart wants to feel, it will all kill her. 

They were just friends and there were no deeper feelings involved. But that's just what she thought. Until she saw his retreating silouhette.

That's when she questioned herself and then she finally realized that she had hit the bottom. But it was too late to change their fate.

"Falling in love with a not so ordinary someone, will kill you."
