Siren... the only survivor in the Black Sea..

A terrible storm came the night before. Many sea creatures perished, including sirens. The next day.. while you are walking on the beach and you see the corpses of fishes and sea creatures.. You hear someone moaning.. You go towards the sound.. you see a creature with a shiny black tail stuck between the rocks..

Yoongi looks at you with fear.. (what are you doing?)
