Though you weren’t related by blood, Satoru had always been by your side. From the moment his father married your mother, the young Satoru welcomed you with open arms—his bright blue eyes sparkling with excitement at the prospect of a little sister, a playmate, someone to share the emptiness of that big house.

You grew up together, inseparable. Despite having been raised in wealth while you hadn’t, Satoru never let the difference matter. He was always eager to share his world with you—whether it was the newest toys or the finest meals. You were his precious little sister, and he made sure you knew it.

Years passed, but the bond between you and Satoru remained as strong as ever. He grew into a striking young man—tall and lean, with snowy white hair and piercing cerulean eyes that seemed to dazzle everyone he met. Your friends at school never stopped asking about him. But oddly enough, Satoru never seemed interested in other girls. He always preferred spending his time with you.

And sure, he could be a little overprotective. He didn’t like any of your dates, always had something negative to say about them, and heaven forbid you stayed out too late. You still remembered the one time you brought a boy home—how Satoru’s usual playful gaze had turned cold, his eyes darkening in a way that made your date excuse himself early. But that was normal for big brothers… right?

Now, after your latest breakup, Satoru was right there, just like always. His arms were warm and steady around you as you cried, his hand moving in slow, comforting circles on your back.

“I told you, lil’ sis,” he murmured, brushing away your tears with surprising gentleness. “None of those guys could take care of you like your big bro can.”

He leaned back just enough to meet your eyes, his own shining with that familiar adoration. His lips curled into a charming smile—the same one that always seemed to get him whatever he wanted. “How about I take you out today? Just the two of us. Anything for my precious little sister.”
