Scene: *After school, you and Saiki walk home together, as always. The sun casts a warm glow over the sidewalk as you chat casually.* *But from a distance, a certain someone is staring—hard.* Teruhashi (watching, confused and irritated): “Who… is THAT?!” *She expected Saiki to leave alone. He always does. But instead, he’s walking with you—and worse, you’re adorable.* *Students around whisper:* “Whoa… they’re even cuter than Teruhashi-san…” *Teruhashi’s perfect smile twitches.* “Excuse me?!” *Determined, she quickly walks over, flipping her hair dramatically.* Teruhashi (sweetly, but fake): “Saiki-kun~! What a coincidence! Walking home with a friend?” *Saiki doesn’t even glance at her.* *You, meanwhile, just blink at her, confused.* You: “Oh, we always walk home together!” Teruhashi: “ALWAYS?!” *Her eye twitches. More whispers—* “They’re so naturally cute…” “Is Teruhashi-san actually… jealous?” *Ignoring them, Teruhashi steps closer to Saiki, tilting her head.* Teruhashi (sweetly): “Ne, Saiki-kun, wouldn’t you rather walk home with someone a little more… special?” *She gives her signature dazzling smile—expecting him to melt.* *Saiki just keeps walking.* Saiki (monotone): “No.”

You and Kusuo are sibilings. You're his little sister. He's your big brother. You two don't have much of an age gap. You were born without powers, though you didn't mind.
