His brother found her on his way home.

"She was unconscious when I found her, hyung. You don't expect me to leave her on the street just like that, right?"

He was watching the strange creature lying on his bed right now. 

It was strange. She was strange.

"So, you decided to keep her or something?"

"Keep her? Hyung, she's not a pet! Well, I thought we can take care of her until she's get better."

"I have to go back to work now. Don't forget to clean up later."

"Hyung!! Don't leave me just like that! Help me take care of her!"

He was already outside the door.

Days passed.

Never he meet her.

Days passed.

Never he talk to her.

Days passed.

Just like that.

One day, she was leaving. She thanked his brother for taking care of her. He was nowhere in sight.

"Noona, are you sure you have to go now? You can barely walk."

"I'm okay, Dongwoonie. I have to go. Thank you so much for everything."

"Please visit me again if you have the time."

"I'm afraid I can't, dear. I'm not even supposed to be here. Farewell, Dongwoonie."

She walked out the door.

And he was walking in.

A fall. A thump.

"Oh, shoot. I'm so sorry."

"It's okay."

He offered his hand. She took it.

Their eyes met.

A gulp. A blink.

"Does it hurt?"

"No, it's okay. I have to go now. Thank you for hospitality, Kikwang-ssi."

She walked out the door.

And he reach out to hold her hand.

Their eyes met. So did their hands.

"Did it hurt?"

"Huh?"

"When you fall from heaven?"

She smiled.

"Yes, Kikwang-ssi. It hurts so much. Now, I'm going back there."

With that, she went.

The house was occupied by only two people now.

It was strangely cold now.

He was working hard while his brother studying hard now.

And still, it was cold.

One day, his brother greeted him home with a huge broad smile.

So wide that he couldn't help but getting worried.

"Did something bad happen?"

"You won't believe it, hyung! I found her again! She was conscious when I found her, hyung. But she's worse now."

He was watching the strange creature lying on his bed right now. 

"Hey. Sorry for intruding again."

"It's okay. It's not like we are super busy."

She tried to laugh but cringed from the pain instead.

"Did it hurt?"

"What?"

"When you fall from heaven?"

She smiled, this time ignoring the pain.

"No."

He raised his eyebrows.

"It hurt worst when I leave you."
