   Summary

   "So, what's bothering you?" the girl prompted her.

   Right. She was supposed to talk. So…

   "Yukkie… Do you think humanity deserves to be saved?" Ruka blurted out without thinking much. Yuki immediately started choking on her drink, her sputters echoing in the evening silence.

   "W-What kind of question is that supposed to be?!" she asked in response.

   Ah. Maybe Ruka shouldn't have said that. She wasn't supposed to tell anyone what she was there for after all.

   But she still wanted that answer. Anything, just to have a starting point.

   "…I had no idea you were thinking about something so serious," Yuki eventually said. "But… of course it deserves it."

   "How can you be so confident about it...?"

   
   

   A love story between the alien tasked with finding someone who can save the world and the human girl who always stays by her side.
