In Yuki's room, she sat straight at her desk, holding a proper book titled Mrs.' Confession to Forbidden Love. She was reading quietly, maintaining an air of perfect elegance.
Unfortunately, Yuki's inner state was far from matching her refined exterior. She was currently being assaulted by an utterly "filthy" noise.
To describe its filthiness, imagine the caw of a crow—that harsh, grating "caw-caw-caw" sound, utterly ominous.
Right now, it was as if a crow were circling Yuki's ears, incessantly "caw-cawing." How could she possibly concentrate on her proper book?
Worse, the crow's call wasn't coming from outside, but from the living room. And why did that voice sound so familiar?
"Agghn~ughn~"
Isn't that her elder sister's voice?
