OrangeJuiceVerse and Orange Slices by @pastorcraigenjoyer
The series that single-handedly sold me on the merits of Style as a ship, but beyond that, this is a terrific little series of oneshots. The characters are very much in character, you still get the more wacky misadventures within a more grounded tone, you get some very sweet-if irreverent-moments between the Main 5 as well as some really nice Style, Kenjorine, and Creek content as well. We see the gang help each other through sickness, injuries, and mental health/neurodivergent struggles as well, so there's that as well. Cannot recommend this series enough.
What Are Friends For? by Tj_animates
For those wanting a fic that highlights friendship rather than romance, this fic shows Clyde supporting Craig as the latter is struggling with a final writing assignment for the year as he keeps doubting himself. Some funny moments and ultimately a very nice fic showing how much Clyde truly cares for his bro.
The Day Liane Died by @roothedei
This one is focused on Cartman moving in with Scott Tenorman following Liane's death, and all that entails. While this is still ongoing, it nevertheless makes for a great character study of Cartman and his relationship with both Liane and Scott, with bits of Kenjorine and Stary sprinkled in as well.
