しまいずまい

Aki is a working adult who shares an apartment with her younger sister Kotomi, a university student. Their days are filled with ordinary routines: Aki goes to her office job, Kotomi attends classes, and they meet at home for meals, chores, and casual conversations. Despite the lack of dramatic events, their interactions are always tinged with humor, as their contrasting personalities and daily mishaps create a warm, comedic atmosphere.

As the sisters navigate the small challenges of cohabitation—from forgotten groceries to conflicting schedules—they rely on each other for support and laughter. The manga focuses on the quiet, funny moments that define their relationship, showing how even the most uneventful days can be meaningful when shared with someone you love.
