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

Two wanderers with no names and no home.

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

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

That was how Baek Seona and Baek Seonha were born.

The two relied heavily on each other.

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

As time passed, their bodies bore the clear marks of enduring those pitch-black times, but they held on by thinking of each other.

For a full 15 years.

Then one day...

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

A B-movie drama centered around 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 got in return was a love full of hostility, violence, and greed.

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

Even so, they yearned for that fantasy.

That was why they escaped from that place.

And they wandered the streets aimlessly.

And leading up to the present...

A secluded alleyway in Gangbuk-gu, Seoul.
