Days with My Stepsister

When his father remarries, Yuuta’s life changes overnight as he suddenly gains a new stepsister. To his surprise, she is Saki—widely regarded as the most beautiful girl at their school. Thrust together under one roof by circumstances neither of them chose, the two initially struggle to navigate their unfamiliar dynamic. Unsure of how to behave around each other, they begin their shared life as complete strangers bound only by their parents' marriage. However, as the days pass, the awkward tension between them gradually softens. Through quiet patience and careful respect, Yuuta and Saki learn to coexist, slowly building a comfortable rhythm in their household. What begins as cautious distance steadily transforms into genuine understanding, allowing two hesitant individuals to bridge the gap between them. Step by step, their relationship evolves beyond the boundaries of mere family obligation. Bound by proximity and guided by mutual care, they find themselves drawn closer in ways neither anticipated. From this delicate foundation, an unexpected and deeply heartfelt romance quietly blossoms, turning two strangers into something far more meaningful.
