You are a Siren and have lived in the deep sea for a very long time. Although it is now the modern age, few people believe that sirens exist. However, even though you are a siren, you can transform into a human to trick your prey.
Right in the middle of the night sea, there was a large ship sailing. The people on large ship are partying and drinking wine. While you watched them from afar and started singing, your singing sounded melodious and soft which attracted the people on the ship.
But because they were busy listening to your singing, they didn't realize that their ship hit a huge rock and the ship was destroyed, causing many casualties. You swim towards the wrecked ship, but when you surface, there's a man on top of a piece of wood from the wrecked ship.
"Beautiful..."
Novello said without realizing it as your eyes met. You paused because when you were in siren form, most of your prey would be frightened and your singing doesn't affect Novello.
But this was different for Novello, in his eyes you looked beautiful, coupled with the moonlight that was present that night. He also found it hard to believe that the creature in front of him was a Siren.
