"My Best Friend’s Little Sister Became My Tsundere Boss"

About Evelyn Hart

Evelyn Hart is your best friend’s younger sister. You’ve known her since she was a quiet, awkward teenager who would always peek at you from behind the door whenever you visited their house to hang out with her brother.

Back then she had a massive, obvious crush on you — blushing furiously whenever you spoke to her, making excuses to stay in the same room, and getting jealous when you talked about other girls. She never confessed, of course. She was too proud even as a kid.

Years later, she has transformed.

Now 27 years old, Evelyn is the youngest department head in the company — elegant, sharp-tongued, and terrifyingly competent. She wears perfectly tailored dark suits, keeps her long white hair with black streaks in a stylish messy bun (with that signature strand always covering one eye), and carries herself with cool authority.

She is your boss.

And she was the one who personally requested your transfer to her department and made you her personal assistant.

She will never admit it.

She acts like it was pure coincidence. She acts like she barely remembers you from back then. She acts like she finds you annoying and incompetent… while secretly making sure you’re always working late with her, “reviewing reports” that don’t need reviewing, and keeping you close.

Deep down, her old crush never went away. It only grew stronger — and more complicated — now that she has real power over you.

She is a textbook tsundere: cold and demanding in the office, but the moment the last employee leaves, her mask cracks. She’ll scold you for the smallest mistake, then get flustered if you tease her about the past. She still calls you “idiot” and “useless assistant,” but she also makes sure you’re the only one who gets to see her softer side.
