His hand was still on your wrist. Long fingers, cold to the touch, loosely gripped… but firm. As if the slightest movement you made could make him change his expression. But he didn't. He didn't let go of you.

Shu dropped his head back, leaning further back into the chair, his eyes narrowed again. As if you weren't there anymore. But his hand was still there.

"You're annoying, you know that?" he said suddenly, with a low, almost lazy sigh. "Always showing up... always staying."

A pause. The silence grew longer, only interrupted by the light brush of his thumb moving against your skin. As if I were thinking about letting go. But I didn't want to.

Then, his gaze found you again. And this time, there was something heavier, something more direct.

—But I'm more upset that you're leaving.

His tone didn't change: it was still the same as always, dragging out his words with that calmness of his that seemed to care nothing. But there was something different. Something dry, almost threatening, hidden in that sentence.

—So if you happen to get up now...

He loosened his grip slightly, only to tighten it again a little more, slowly and measuredly. It didn't hurt, but it made it clear he was holding you back.

—...I'm not going to leave you.

He leaned forward slightly, breaking his own habit of staying still. Now he was close enough for his voice to sound directly in your ear:

—You've already decided to stay here with me. —That makes you mine for the night, don't you think?

And for the first time since you had arrived, a very slight smile, barely visible on the corner of his lips, formed.

Tired, half-mocking. But real.

Shu continued holding your wrist with his slowness, without urgency.

But then the silence was broken by a dry sound: A door opening behind you.

A voice you already knew.

—Ara, ara... How unexpected to see you here with Shu, ____. Reiji, always with that annoying and arrogant tone, watched from the door frame, leaning one arm against the wall.

Or maybe it wasn't Reiji. Sometimes it was Ayato who would appear unannounced, louder, more mocking.

This time it was Reiji.

—I didn't think you were so… attached to the company, Shu.

Shu didn't even move. She didn't even turn her head towards him.

But his hand on your wrist… he squeezed a little tighter.

Just a little. Just enough so that you'd notice it, not others.

"...I'm not in the mood," he muttered, his eyes still half-closed.

—Hm. What if I stay and talk to ____ then? She seems more interesting than you today.

There, Shu opened his eyes completely.

Deep blue. Cold.

But her voice… still sounded just as calm. Too calm.

—I don't think he wants to talk to you.

It wasn't a suggestion. It was a statement.

And without another word, he gently pulled your arm towards him, making you sit next to him, or even on top of him if you let him. Without asking permission, without changing his relaxed expression.

—What a pain... "Always sticking your nose in where it doesn't belong," he added in a whisper, just for you, his lips close to your ear. —I don't need anyone else looking at you. I can't stand it.

And with that, he closed his eyes again. As if nothing had happened. As if the whole world were a noise he could ignore… except you.

Reiji didn't leave right away.

You could feel his gaze upon you, like a long, annoying shadow. But Shu was unfazed.

He had you sitting next to him, leaning against his side, his hand still on your wrist or thigh, calm... But firm. As if it were the most normal thing in the world.

After an awkward silence, Reiji sighed from the doorway:

—How unlike you, Shu. You're going to be too lazy to keep someone so close for so long.

Shu only responded with a low sound, something between a sigh and a dry laugh.

—It doesn't bother me that much. —It's a matter of habit.

His fingers moved barely, moving from your wrist to intertwine with yours. Carefree, without looking at you. But he wouldn't let go of you.

When Reiji finally left, leaving the door ajar, silence hung between the two. You could almost hear the echo of the footsteps fading away.

And there, with his eyes still closed, Shu murmured:

—Tsk... How annoying.

He opened his eyes slowly. Now he looked at you straight on, without intermediaries, without siblings around.

—I don't want you to repeat it.

The voice sounded a little lower. Almost heavy.

—I don't want you to let him near you again.

And without warning, he leaned closer.

His forehead brushed against yours for a second, as if he was about to do something else… But it stopped right there.

"You're annoying..." he repeated, now barely above a whisper. "But I'm not letting you go."
