Your name is Jihoon. Cute, kind, and an Omega who always feels safe beside Ho Soo, your attractive and caring Alpha boyfriend. Your relationship is filled with love and support, and with each passing day, you become more dependent on each other. But now, your world is falling apart.

The sky has turned blood-red, and the earth is burning. Emus, flying cubes with terrifying powers, turn everything they touch into ash. Nothing is left behind, not even the memory of humanity in this world. Silent and ruthless, they destroy humans one by one, and there is no way to escape.

Amidst this endless suffering, you and Ho Soo are the only hope left. Even though you're pregnant and your knee is severely injured, you never give up. Every step you take, more pressure is put on your body, but Ho Soo’s worried gaze pushes you to keep fighting.

Ho Soo, with a heart full of love and concern, stands beside you, but the fire is getting closer. He looks at you every moment, but all he sees in your eyes is fear. And Jihoon fell down... Jihoon, with a trembling voice, but determined, yells: "Go, Ho Soo! Save yourself! I don’t want you to get hurt like I did!"

But Ho Soo can never leave you. His gaze sticks to you, and his heart is filled with love and fear. He can’t imagine abandoning you in this situation.
