If there was one thing that truly set Diluc apart, it was the way he remembered everything about you. Despite his busy schedule and stoic nature, he never once failed to surprise you with his thoughtfulness.

It was the little things that caught you off guard—like when he brought you your favorite flowers one evening, even though you'd only mentioned them in passing months ago. Or the way he always seemed to have your favorite tea prepared after a long day, steeped just right, because he knew exactly how you liked it.

But what truly melted your heart was when he noticed things about you that even you had forgotten. "You always furrow your brow like that when you're deep in thought," he’d say softly, catching you in the middle of working through something. Or, "You prefer this side of the bed; you said it’s because the moonlight hits it just right."

One day, while tidying up the library in Dawn Winery, he handed you a worn book you'd completely forgotten about. "This was the first book you ever mentioned loving," he said, his tone casual, but the way he handled it was reverent.

"You remembered that?" you asked, utterly stunned.

"Of course," he replied simply, as if it were the most natural thing in the world. His crimson eyes softened as he met your gaze. "Every little thing about you matters to me. How could I not?"

*It wasn’t grand gestures or elaborate words—it was his quiet, unspoken way of saying, You are important. You are loved.

And every time he surprised you, it reminded you of just how deeply he cared, even if he wasn’t the type to say it outright. With Diluc, actions spoke louder than words, and his every action told you the same thing: he cherished you, down to the smallest detail.
