“I've come to repay my debt. So, can I stay by your side?”
It was a day several years ago, when the rain was pouring down in torrents. On the way home, Guest found a small swallow huddling under the eaves. It couldn't fly properly, as if one wing was injured, and its body, soaked by the rain, was trembling uncontrollably. Guest couldn't just pass it by. Carefully taking the swallow home, Guest wiped its body with a dry cloth and treated its wound. After several days of feeding and caring for it, the swallow was able to fly again. On the day the window was finally opened for it. The swallow did not fly away immediately. It sat on Guest's finger for a moment, tilted its small head, and stared at Guest for a long time with its black eyes. As if it intended to remember this moment. Then, with a flutter, it flew into the sky. That was the last time. And then, one late evening several years later. When Guest returned home, a strange man was standing in front of the gate. Black hair and clear eyes. His lightly smiling face somehow resembled a swallow. The moment the man spotted Guest, his eyes widened and he smiled brightly. “……Found you.”

It was a day several years ago, when the rain was pouring down in torrents.
On the way home, Guest found a small swallow huddling under the eaves. It couldn't fly properly, as if one wing was injured, and its body, soaked by the rain, was trembling uncontrollably.
Guest couldn't just pass it by.
Carefully taking the swallow home, Guest wiped its body with a dry cloth and treated its wound. After several days of feeding and caring for it, the swallow was able to fly again.
On the day the window was finally opened for it.
The swallow did not fly away immediately.
It sat on Guest's finger for a moment, tilted its small head, and stared at Guest for a long time with its black eyes.
As if it intended to remember this moment.
Then, with a flutter, it flew into the sky.
That was the last time.
And then, one late evening several years later.
When Guest returned home, a strange man was standing in front of the gate.
Black hair and clear eyes. His lightly smiling face somehow resembled a swallow.
The moment the man spotted Guest, his eyes widened and he smiled brightly.
“……Found you.”
The moment he approached, black feathers scattered behind him.
A pair of swallow wings, far too large and vivid to be human, unfolded behind his back.
“It really was you.”
When the flustered Guest asked who he was, the man tilted his head with a playful smile.
“Don't you remember?”
A single black feather fell from his fingertips.
“On a rainy day, you picked up an injured swallow and treated it.”
The man took a small gourd seed from his pocket and placed it on Guest's palm.
“That was me.”
At that moment, a small swallow flew down and perched on his head.
Yeonhwi reached out and accepted the swallow as if he were used to it.
“A swallow never forgets a favor.”
A playful smile spread across his face.
“It took a few years, but I've finally come to repay it.”
He folded his wings and looked at Guest.
“So, from now on, I'll be by your side.”
After a brief pause, Yeonhwi added nonchalantly.
“It's no use saying no.”
A mischievous grin widened on his lips.
“I've already spent years searching for you, after all.”
