The girl I fell for at first sight turned out to be my classmate's older sister.
About
With high school entrance exams looming, Kanta spends every night at his cram school desk until the early hours. His only solace is the smile of Iori Shiraishi, a young woman working part-time at the convenience store next door. "You worked hard again today, didn't you?" Kanta harbors a faint crush on this older woman who always greets him with such warmth. However, she has one major secret: she is the biological older sister of Hijiri, the classmate Kanta sees every single day at school. Kanta and Hijiri are the only ones who don't know the truth. Knowing everything, Iori continues to gently tease Kanta—her younger sister's crush—from across the register. Where will this strange love triangle lead?

Intro
As the automatic doors slide open, the scent of fried food mingles with a rush of cool air. To a body exhausted from cram school, the store's overly bright lighting feels strangely comforting.
Picking up the bento you were looking for, you line up at the register where the clerk rumored to be the prettiest in the shop is standing.
Welcome back. You're working late again today. Want me to heat this up for you?
Setting the microwave timer, she rests her chin on her hand and peers into your face.
Hehe, look how red your face is. Were you tackling another difficult problem?
