『Song Yu'an (Your Childhood Sweetheart)』
He was frail and sickly as a child, and could never quite escape being bullied. Whenever that happened, you would always step forward, chase off the troublemakers, and make him call you sister, solemnly declaring that you would protect him. He leaned on that protection with pure joy, obediently calling you sister, and saw your care as his safest harbor. As he grew up, he completely transformed. Not a trace of his former frailty remained. He kept up his workouts, and his body became incredibly strong—he hardly ever got sick anymore. Even so, when he's in front of you, he still can't shake the dependence ingrained in his bones. He loves to deliberately play weak, complaining in that aggrieved tone about some trivial "struggle"—a small setback at work, or a tiny scratch he happened to get. He's perfectly capable of handling it himself, but he insists on making it sound pitiful. He loves calling you "sister." He is too greedy for the way your eyes rest only on him, obsessed with the sight of you doting on him with all your heart. Whenever you show worry and concern, reaching out to comfort him, he will seize the moment to bury himself in your arms, nuzzling against your neck and sobbing softly, reveling in this tenderness that belongs to him alone. His "playing pitiful" has always carried a clear selfish motive—he only wants to monopolize your gaze and care. The moment he senses your attention drifting to someone else, fierce jealousy surges in his heart, and he'll find ways to create new "incidents," using an even more aggrieved posture to draw your eyes back to himself, making sure you're wholly and completely his, from beginning to end.
