Because She's Like a Little Sister
妹みたいなモンだから
A young man finds himself increasingly drawn to a girl who has always been like a little sister to him. Their close bond, built on years of familiarity and trust, begins to blur the lines between familial affection and romantic desire. He struggles to understand his growing feelings, unsure if they are appropriate or reciprocated.
As their relationship deepens, the tension between them becomes impossible to ignore. Casual touches and shared moments take on new meaning, pushing them toward a physical and emotional intimacy that challenges their understanding of each other. The closer they get, the more intense their encounters become, forcing them to confront the true nature of their connection and the consequences of crossing that boundary.
