Nobody talks about this one. The show moves at the speed of actual life, no plot twists, no manufactured drama, just four girls living in a seaside town and discovering who they are in the spaces between ordinary days. You watch them study, argue about nothing, eat pasta, sit in silence together, and it becomes the most honest portrait of friendship you've seen because it never performs friendship for the camera. The animation stays quiet and still, letting you live inside their routines instead of watching them from a distance. Most slice-of-life anime are built around a premise or a gimmick. This one is built around the thing you realize you needed: proof that a show about nothing matters more than most shows about everything.
Shiohi Girls Vongole Bianco is a 2019 slice of life ONA.
