Probably 1-2 years older (cuz her younger sister referred to the main character as senpai, and main character referred to older sister as senpai, high school in Japan is 3 years)
Ohhhhhh
She fais she was three years older, but tbh it’s still a little wrong in my opinion since the maturity difference between the younger one and the older one at that age is still pretty different. I feel like if they were both adults, the 3 years age gap wouldn’t be as bad
I just read the latest ch and it would have been fine if it was 1 year at the very least but then the girl said that she finished highschool which is 3yrs for them and the other one had just started so
I for got to put or less than a year
Wait go on a date how old Is the sister
