Days with My Stepsister

When his father remarries, high school student Yuta Asamura suddenly finds himself living under the same roof as his new stepsister, Saki Ayase. To complicate matters further, Saki happens to be widely regarded as the most attractive girl in his grade. Both teenagers carry deep emotional scars from their parents’ troubled divorces, leaving them wary of forming attachments that might ultimately lead to more heartbreak. Determined to avoid unnecessary drama and protect themselves from potential pain, Yuta and Saki make a mutual pact to maintain a polite but careful distance from one another within their shared home. However, navigating daily life together proves far more complex than either anticipated. What begins as a cautious, respectful camaraderie gradually shifts as they accumulate shared experiences and quiet moments of understanding. The walls they built to keep each other at arm’s length slowly begin to erode, replaced by an unfamiliar closeness neither knows how to categorize. As their bond deepens into something far more profound than simple cohabitation, both are left questioning the true nature of their feelings. They must confront whether this growing connection is merely admiration, the natural affection of newfound family, or the beginning of something entirely different and far more complicated.
