The sun was high when the doorbell rang again.
Aya was out buying groceries.
Rikuto opened the door — expecting a delivery.
Instead…
Rina.
The youngest of the three sisters. Barely twenty-one. Wild, radiant, and utterly unfiltered.
She stood in short denim shorts and a crop top that barely covered her underbust. Her flat stomach was pierced with a silver ring, and her long caramel-brown hair was tied up in a playful bun.
Sunglasses pushed atop her head.
Bubblegum between her lips.
She leaned on the doorframe with a cocky grin.
"Well well well," she smirked. "Is my boring brother-in-law finally hot now, or am I dreaming?"
Rikuto blinked. "...Rina."
She stepped inside without waiting.
"You smell good," she said bluntly, eyes already scanning his body. He wore nothing but a plain black t-shirt and sweats. "Been hitting the gym? Or did my sister start feeding you actual protein instead of tofu sadness?"
Rikuto chuckled, closing the door. "You're not exactly the shy type, huh?"
She dropped her shoes and flopped onto the couch, one leg swinging.
"Oh please. You used to avoid eye contact with me. Now look at you — standing there like you own the place." She sucked her gum noisily. "I was curious."
He tilted his head. "About me?"
"Mhm."

She stretched her arms, deliberately arching her back, her breasts pushing against the fabric of her top.
"So," she said. "What changed?"
"You mean physically?" he asked, walking into the kitchen.
"No, dummy. You. You used to flinch when mom scolded you. Now you've got this… vibe."
He looked at her.
Unblinking. Calm.
"I finally remembered who I am," he said coolly. "And started acting like it."
She paused — the gum snap froze mid-bubble.
That wasn't the Rikuto she remembered.
She licked her lips slowly. "Damn. You're kinda hot now, you know?"
He raised a brow. "And you're still a brat."
She gasped theatrically, placing a hand over her chest. "Excuse me?! You can't call a lady that!"
"You're not acting like one."

Rina's pulse quickens. Arousal – 34%
Her breath caught for a second.
She liked being pushed.
She stood up, walking closer. "You're lucky I'm cute. Most girls would be mad."
He stepped toward her too, closing the gap just enough.
"I've seen cute. You're more like trouble wrapped in denim."
She blinked — cheeks flushing lightly.
But she didn't back down.
Instead, her voice lowered, just a notch.
"Would it be so bad if I was?"

She smirked again, but now her posture was a little tighter. Her breaths a little shallower.
She flicked his shirt collar teasingly. "If you weren't my sister's husband, I'd test this new attitude of yours."
He leaned just slightly closer. Just enough for her to feel his breath.
"And if I weren't your sister's husband, I might let you."
Their eyes locked.
Heat.
Unspoken.
Thick.
Just then, the front door opened.
Aya walked in, grocery bags in hand.
"Rina?" she blinked. "You're here?"
Rina stepped back — cool as ever. "Hey sis. Just dropped by to tease your man. He's got a backbone now."
Aya laughed. "I know. Cute, right?"
Rina's smile stayed… but her eyes flicked back toward Rikuto once more.
That wasn't "cute."
That was dangerous.
And she liked dangerous.
