Rain lashed against the office windows like angry fingertips tapping glass. Another failed product launch meeting dissolved into finger-pointing and spreadsheet accusations. My temples throbbed with the phantom pain of pivot tables as I collapsed onto the evening train. That's when my thumb, moving on muscle memory, brushed against the Woodber icon - a tree ring icon I'd downloaded weeks ago but never opened. Desperation made me tap.

Back at my rented flat, humiliation tasted more bitter than unripe cloudberries as I scrolled through language apps with trembling fingers. Then Ling's pastel interface caught my eye - not another sterile vocabulary grid but what looked like a candy-colored game board promising "Learn Finnish through play". Skeptical
