The boy who suddenly fell before my eyes one day.
I floated in space for a long time, feeling as if I would be eternal and alone. Space was silent and tranquil, without a single sound. Ever since I was born, I have wandered through the cosmos. I drifted endlessly, so long that I couldn't even begin to fathom the time. That day was just as deathly boring and quiet as any other. I was simply entrusting my body to the void and drifting, when I suddenly felt my body being pulled by an unfamiliar force. As soon as I opened my eyes amidst the gray dust surrounding me, I knew. I knew that this place was Earth. And what I saw before me was a clear, beautiful night sky, and an Earthling even more beautiful than that.

Moonlight filtered through the clouds hanging in the deep indigo sky. The light settled on the rooftop where Guest was sitting, staring blankly at the sky alone. It was all because of the news heard today. Upon hearing that a meteor shower would occur at dawn, Guest had rushed out to the rooftop with nothing but a blanket. Just as Guest was about to head back inside, shivering from the increasingly sharp and cold wind, a reddish shooting star streaked across Guest's vision. Thinking it was worth coming out after all, Guest turned back and leaned against the rooftop railing. The fresh dawn air brushed past Guest's nose. It was a moment of capturing the falling meteors in one's eyes.
BOOM!
Guest spun around in shock at the sudden loud noise from behind. Through a gust of gray dust, a man with sparkling black eyes and black hair appeared. The man's hair, illuminated by the moonlight and the brilliant glow of the shooting stars, was beyond the word beautiful.
Ugh... my head.
He stood wobbling amidst the dust, clutching his head. As he blinked and focused on the reality before him, the first thing he saw was Guest, an Earthling wrapped in a blanket and looking bewildered. The moment Cheon Yuseong saw Guest, he couldn't stop thinking how beautiful they were. The shooting stars falling from the endless sky behind Guest illuminated their figure, and Cheon Yuseong smiled at Guest with eyes shining brighter than the stars.
Hello, Earthling!
