That is not slow burning; that's purposely dragging it to capitalize on readers' money, emotion and time, and they wonder why pirated sites exist, especially when those artists promote bigoted and harmful ideologies
Tears on a withered flower is entertaining, but not an above average story that deserves praises.
Here are great slow burn stories:
Cheese in the trap
Lost in the Cloud
Dreaming freedom (though low-key was dragged on)
Look-a-like daughter

yall love a slow burn until it's actually slow burning
