The Annoying Older Girl Next Door

When the protagonist was a sickly child shunned by his peers, Eun-Seol, the kind older girl next door, became his sole companion. She offered him comfort and unwavering care during his most vulnerable years, filling the void left by friends who refused to play with him. Her gentle presence was a lifeline back then, but what began as childhood compassion has evolved into an inescapable burden. Now that he has grown into a young adult attending college, Eun-Seol refuses to adjust her behavior. She continues to dote on him relentlessly, clinging to him and treating him as though he were still a helpless little boy. Her overbearing affection has severely damaged his social standing, earning him the humiliating nickname "Baby" among his classmates and effectively turning him into a complete loner. Every attempt at independence is smothered by her lingering maternal instincts. Desperate to reclaim his dignity and build a normal life, the protagonist realizes that passive frustration will no longer suffice. To escape the shadow of his childhood and shed the infantilizing label forced upon him, he must fundamentally change Eun-Seol's perception of him. His only path forward is to make her finally see him not as the fragile boy she once protected, but as a man.
