Aniki to Isshoja Nemurenai

Eight years ago, their parents' remarriage bound them together as brothers. Haruto, six years the protagonist's senior, is not related by blood, yet he has always shown unwavering warmth and care. Over the years, his older brother's gentle devotion blurred the lines of familial affection, quietly nurturing a deep-seated desire within the younger sibling to keep Haruto entirely to himself. Terrified of what might happen if these forbidden feelings were ever exposed, the protagonist carefully guards this secret burden, desperate to maintain the illusion of a normal brotherly bond. Seeking independence and distance from the overwhelming emotions tied to his stepbrother, the protagonist moves out to begin university life alone. For the first time, physical separation offers a fragile sense of relief and the hope of moving forward without the constant temptation of Haruto's presence. However, that newfound solitude proves short-lived when his devoted older brother unexpectedly tracks him down and insists on inserting himself back into his daily routine. With Haruto now closing the distance between them once again, the protagonist is forced to confront the very desires he tried so hard to escape, leaving him terrified that his carefully hidden emotions will finally be brought to light.
