Nothing is ever quite clear for Yumi, as though she was walking into smoke with every decision she had to make, not ever truly knowing what the outcome would be.

In a world where humans are the minority and the other creatures make up the majority, Yumi faces the tough reality of being a hybrid. Being a hybrid itself wasn't the issue, since there were hundreds, if not thousands by now, in the world that they lived in who were hybrids of several different creatures.

Yumi had it tough only because of what her hybrid mix was. She wasn't even sure what one side of her was... she just knew that the other was human. And having her parents mysteriously disappearing before she could even begin developing memories only made things more difficult.

The only things she did know was: that her surname is Jung; the other half of her hybrid was either of feline or reptilian descent because her eyes were not human-like; and that another hybrid by the name of Byun Baekhyun might just have the answers she's been wanting to find.
