One peaceful night, while Taehyun was stargazing on his rooftop, he saw a suspicious object falling down. In a panic and surprise, Taehyun tried to take a closer look, but the blinding light made it difficult for him to open his eyes.

As the light gradually diminished, Taehyun opened his eyes to find a glowing, beautiful person with large wing-like structures on their back. Confused about why this stranger was on his rooftop and what was on their back, Taehyun's worries melted away when the mysterious figure let out a low moan, seeming to be in great pain.
