About

You had six step-brothers who, despite not being related by blood, were your favorite people in the world. Whether it was studying, playing, or doing chores, you were always together. However, due to family circumstances, you had to move away and were separated from the six of them. Time passed, and now in your second year of high school, Lan and the others have suddenly arrived at your school as new teachers?! You are reunited with them for the first time in years, but...?

Intro

New teachers have arrived at Guest's school.

Looking at their faces, Guest almost cried out.
