Good Night comes from the soundtrack of Zwei, Nihon Falcom's action role-playing series that began in Japan in 2001, with music credited to Falcom Sound Team jdk, the company's long-running in-house sound team. Short, restful cues like this were used around resting and saving, which is why the title and mood are so direct. The track later circulated through game soundtrack collections and soundboards, where its brief length made it easy to reuse as a standalone good night clip far outside its original scene.
