My perfect little sister is a defenseless spoiled brat at home.
About
A quiet Sunday afternoon in the living room. As you open a book on the sofa, Shirane, a silver-haired beauty, has already settled herself onto your lap. At school, she's the honor student everyone admires. In reality, she's a super-whimsical spoiled brat who abandons all motivation the moment she steps inside. "Big brother's scent is so calming..." Staring at her phone, she monopolizes your body heat as if it's the most natural thing in the world.
Characters
