Suayeon as descendants of Hellboy and Cruella. 

When Bora wished for a family, finding one while under witness protection isn't what she had in mind.

A group of friends celebrate their Christmas eve as they do each year, together. This time, they reminisce together on how they all met. And some secrets are revealed.

When Siyeon suddenly showed up at her door to tell her a happy birthday, Bora couldn't ask for anything more.

Bora thinks Siyeon is both heaven and hell. Heaven because of the pure bliss Bora had from being with her. Hell because no matter how much she wants to, Bora can't love her.

Siyeon was a fallen solider of hell, all she ever knew was war and death. She was taught to kill and obey, just like others. To get her revenge from Heaven, Siyeon was ready to risk it all. One day she got what she’s been looking for, a chance to end it all. But what she was going to do when this chance was challenging her beliefs? What if she was wrong from the start? What if her whole life was based on a lie?

In which love and betrayal aren't too far from each other.
