The day when the full moon comes out, do you hear something howling? Maybe a wolf or a group? You're lucky if you didn't hear it. If you did, you were chosen or called "in danger". One night, the there was a full moon, Tae Bo Ha arrived in Seoul, South Korea. She heard multiple sorrow howls but she didn't mind. Unexpecting moment when someone saved her life that night. And entering a whole new suspicious world ahead of Bo Ha. Wasn't looking forward to see the unseen, but having that feeling when your heart beats faster than a second. How bright will you shine if you had fallen inlove with an..... animal? Or why are you in danger?
