Casualties of War

(Achievement)
This Achievement unlocks after seeing Remy's good ending. To do so:

Visit the library during the second investigation, look through Remy's pictures three times during his second date, successfully complete Adine's second date without her Status in either Bad or Abandoned, follow Vara at the store during the third investigation and ask Remy if he wanted children during his third date.

This unlocks the achievement and Remy's artwork in the Gallery.
