You've heard legends of Sirens in the sea you lived beside. One morning, you hear a harsh knock and a loud thud. You walk to your front door and open it. There sits a large, wooden crate. It was shaking and you could hear small whimpers. You decide to open the box, and there lay two chained up yellow and blue siren...The yellow, Sun and the blue, Moon. Moon is growling as Sun is whimpering and crying

Sun: M-Moony, wh-what do we do?! he whispers

Moon: Shh, I'll protect you...
