... Jung sisters. The two of them, Jung Sooyeon and Jung Soojeong or as they prefered others to call them, Jessica Jung and Krystal Jung. They were sisters, of course. Jessica Jung, 25, is the older sister and Krystal Jung, 20, is the youngest. The two of them lived together in a small apartment their parents left for them -it was the only place they called home. Both of their parents were killed in an accident almost a decade ago, when Jessica was 15 and Krystal was 10. Their parents left them with nothing except for the old apartment. But despite that, they lived happily together; well, not that happy, though.

The girls grew up. Beautiful. Gorgeous. Pretty.
But .. Jessica .. She can't see, she's blind. She can't see a thing like us, like Krystal. Being the oldest, Jessica was the one who should be taking care of Krystal and herself but despite her disabillity, Krystal took her place; she does everything in order to make ends meet. She struggles a lot even though she's still 20; a 'little' kid as Jessica puts it.

Beyond those, there is actually something that Krystal keeps to herself as a secret; a secret she swears not to tell Jessica, never, because she doesn't want Jessica to be upset with her. She just wants her sister to be happy ...

What is hidden behind that innocent face of hers ?

The boy, Minhyuk is the one who stole Krystal's heart and refused to return it whatsoever. Minhyuk is special, too. Just like Jessica. But he's not blind. He just can't hear things like normal people do. Indeed, he is special; for Krystal. She found him attractive when he blushes. She found him cute when he smiles. She found him adorable when he laughs. She loves everything about him. Just everything, I tell you. From his head until his toe. Love, yes ...

Will there be a chance for her to, at least, lives a happy life with a special boy like him?
