Main Plot :
Hori-san to Miyamura-kun (堀さんと宮村くん, lit. “Hori and Miyamura”) is a Japanese shōnen web manga series written and illustrated by Hiroki Adachi, under the pseudonym Hero.
Kyoko Hori is a bright and popular high school student, in contrast to her classmate Izumi Miyamura, a gloomy and seemingly nerdy glasses-wearing child.
Hori is a homebody who dresses down and looks after her younger brother Souta when she is not at school.
She takes every attempt to hide this from her classmates.
Souta was assisted by someone with numerous earrings and tattoos, as well as a punk-styled look, when he came home with a nosebleed one day.
They agree to keep their true identities concealed from their peers, but they begin to relate to each other as friends and then as a couple. (Source – Wikipedia)
