Aneki My Sweet Elder Sister The Animation Verified -

Most stories involve interactions with older female authority figures or upperclassmen rather than literal sisters.

The protagonist, a nameless young man, returns to his family home after a long absence. His sister, "Aneki" — a term that in Japanese carries both familiarity and a hint of old-fashioned respect — has not changed. She still arranges his chopsticks the way he likes, remembers his fear of thunderstorms, and teases him with the same sharp-but-soft affection she used when they were children. Yet everything has changed. The space between them is now measured not in feet but in unspoken regrets. aneki my sweet elder sister the animation verified
