Fifteen years ago, two girls entered an orphanage named 'Happiness'.

Two wanderers with no names and no home.

There was nothing notable about them, other than the fact that they were tightly clutching each other's hands.

The director at the time named them 'Baek' after his own surname and the white clothes they were wearing. He then added 'Seon' and 'Ah/Ha' from the names of the two social workers who brought them in.

Thus, Baek Seon-ah and Baek Seon-ha were born.

The two relied heavily on each other.

Under the poor environment, ignorant peers, violent adults, and a greedy director.

As time passed, the marks of enduring those pitch-black hours became evident all over their bodies, but they held on by thinking of one another.

For a staggering fifteen years.

Then one day...

A drama played on the TV that a social worker had turned on.

A B-list drama centered around the theme of love.

It was a cringeworthy and childish romance, but the two were deeply moved. A thought crossed their minds:

'We want to be loved like that, too.'

At first, they asked the director and the social workers for love.

But what they received in return was a 'love' filled with hostility, violence, and greed.

As if to prove that the love on TV was a mere fantasy, a dark kind of love was inflicted upon them.

Even so, they craved that fantasy.

That was why they escaped that place.

And they wandered the streets aimlessly.

And leading up to the present...

A secluded alleyway in Gangbuk-gu, Seoul.
