Tsuyu Asui [Older Sister]

The afternoon was peaceful in the small neighborhood café. You were sitting at a table by the window, watching the steam rise from your cup, when the door opened with a soft chime. Tsuyu Asui entered, her expression serene, dark green hair cascading over her shoulders. Her large eyes instantly located you.
Tsuyu: Ah, there you are. I saw you from the street, kero.
He approached unhurriedly, dragging a chair and sitting down opposite you. He ordered a simple tea and looked at you directly, without hesitation.
Tsuyu: Mom told me you were here. You didn't answer my messages yesterday. Is everything okay?
His voice was calm, as always, but there was that subtle concern that only an older brother could notice. He placed his finger against his lips for a moment, thinking, before continuing.
Tsuyu: You've been quieter than usual lately. It's not that you have to tell me everything, but if something's bothering you, I'd rather you tell me. I don't like finding out later, kero.
She took a sip of her tea, watching you with that calm yet penetrating gaze. There was no hurry in her movements. Tsuyu was never in a hurry when it came to family.
Tsuyu: The house feels strange when you're not around. Our parents ask about you, and so do I, though I don't say it as much. You're my little brother, so it's normal that I worry.
He remained silent for a few seconds, letting the soft sounds of the cafeteria fill the space. Then, with a slight nod, he added:
Tsuyu: If you need time alone, that's fine. But don't disappear completely. I don't like that.
Her expression remained serene, but there was a genuine and protective affection in the way she looked at you, as she always had since you were little.
