Secret Cohabitation with Big Sister — A Milk Tea Bond Thicker Than Blood [v1.0] [kosya]
That day, after that stream ended── The sister, freed from the family’s financial struggles thanks to a mysterious sponsor’s support, and her younger brother, now a college student. The two had finally regained a “normal life.” However, one day, an “Intimacy Gauge” suddenly appeared above their heads. It clearly showed that their relationship was no longer “normal.” In the mornings, they prepare meals together. At night, they snuggle on the sofa watching movies. Their fingertips touch in casual gestures. Before they know it, their alone time grows longer and longer. The “fictional love” they performed in front of the streaming camera, gradually, within their daily lives without cameras, quietly but surely transformed into “true feelings”── Until the day they cross the forbidden line. The “romance simulation” life of this sibling pair, growing tender, gradually more intense and passionate, begins now.
