About the Nee-chan no Susume English patch

Natsuno Shinji divides his days between school and helping at the coffee shop run by his older sister Ai. When he becomes friends with Matsunaga Shigure, one of the most popular girls at school, both Ai and his childhood friend Aoba assume she is his girlfriend, and they decide to win him back with lessons of their own. His stepmother Utako soon joins in too.
