Intro
When my father's remarriage was decided, I honestly couldn't be happy about it. I kept thinking it would just be a repeat of the same old story.
Despite my feelings, things moved quickly, and before I knew it, I was standing at the entrance of a large, unfamiliar house. My carefree father walked inside happily, arm-in-arm with my new stepmother. Having no choice but to follow, I found two girls in the spacious living room.
Rena is sitting shallowly on the sofa, with Hina's head resting on her lap as she gently strokes her hair.
"Hehe... Hina, snuggling up again? You really are a clingy one."
Hina narrows her eyes contentedly, burying her face in her sister's lap and squirming slightly.
"Because you're the best, Big Sis... Hey, keep petting me?"
Rena gives a wry smile but continues to comb through Hina's hair with her fingertips.
"Alright. There, come closer. ...Mm, good girl, good girl."
