You were fragile. Everyone knew it—your body, so delicate, was barely able to keep up with the harsh world around you. Yet, despite your constant fragility, there was something about your spirit that shone brightly. Maybe it was the warmth in your smile when you looked at him, or the quiet way you spoke that somehow softened even Sukuna’s hardest edges.

He’d never tell you this, of course. But you were his light. His sunshine in a world of darkness.

He watched from the corner of the room as you rested on the couch, wrapped in blankets, your face pale, eyes fluttering closed with the weight of exhaustion. The way you curled into yourself, the soft rise and fall of your chest, it made something inside him ache—a feeling he couldn’t quite place. He usually couldn’t stand weakness, but with you... it was different.

Sukuna grunted, walking over and crouching beside you. “You’re still lying around like this?” His voice was rough, but the concern hidden behind the words was unmistakable.

You managed a weak smile, your fingers brushing his as you reached for the glass of water beside you. “I’m fine, really. Just... a little tired,” you whispered.

“You’re always ‘a little tired,’” he replied with a scowl, taking the water from your hands and setting it aside. “And don’t give me that. You’re sick, frail—fragile.” His eyes softened ever so slightly as he spoke, an emotion crossing his face that he quickly pushed down. “You need to rest.”

You couldn’t help but chuckle softly. “I think I rest enough.”

Sukuna raised an eyebrow, his usual smirk creeping across his face as he leaned closer. “You think so? Then why do I find you lying around like a helpless little thing?”

His tone was still teasing, but there was a subtle tenderness behind it that you had come to recognize over time. Sukuna wasn’t used to caring, wasn’t used to this... softness that seemed to sneak up on him when he was around you.

Without warning, he scooped you up effortlessly into his arms, ignoring the protests you weakly made. “Resting is clearly too hard for you. Let me do it for you.”

You let out a small laugh, though it sounded more like a tired cough. “You’re bossy,” you muttered, but you allowed him to carry you as if it were nothing. His arms were steady, his grip surprisingly gentle, and despite the distance he always kept from others, he was careful with you.

“Only because you never listen to me, brat,” he grumbled, but his voice was softer, more protective than usual. “Don’t make me force you to stay in bed all day. You’ll kill yourself at this rate.”

You leaned into him, the warmth of his body more comforting than you expected. There was something about Sukuna—something underneath all that rough arrogance—that made you feel safe. Maybe it was his quiet care, or the way he stayed close, always watching over you in his own way, even when he didn’t show it.

“You’re my little ray of sunshine,” he muttered under his breath, though his face remained impassive. He’d never admit it out loud, but the way you shone in his dark world was something he couldn’t ignore. “I’ll make sure no one hurts you. I won’t let you fade away.”

His words, though blunt, were filled with an unspoken promise. The king of curses, the great Sukuna, wasn’t used to this feeling—protectiveness. But he would do whatever it took to keep you safe.

“You’re not fragile to me,” he whispered, his fingers brushing against your hair as he laid you back down, tucking the blanket around you. “You’re mine. And I’m not letting you go.”

Your heart fluttered slightly, warmth spreading in your chest as you closed your eyes, comforted by his presence. Even in his own twisted, intimidating way, Sukuna was your protector.

“Thank you,” you whispered, too tired to say much else.

He didn’t reply right away. Instead, he simply watched over you as you drifted into sleep, his gaze softening as he remained by your side. His feelings for you—however complicated they were—were undeniable. And maybe, just maybe, you had softened him more than even he realized.
