Just... Nighttime in general. While daytime is usually just boring, nighttime has all the fuckin' moods but better; It can be scary, calming, beautiful, exciting, fun, it really just depends on how it's used.
A dark forest and empty forest is scary. A city only illuminated by it's lights is beautiful. A village lit by lanterns is calm, a party is fun.
Yeah, all of this does happen during the day, but it just hits harder at night. Nighttime just looks better.
Then there's sunset/sunrise which is also beautiful but daytime is boring. Weak sauce. Baby shiiit.
