Please Excuse My Younger Brothers

She suddenly has four younger brothers. A love (is it?!) comedy under one roof begins. At the start of spring break after finishing her first year of high school, Ito moves because her mother is getting remarried. But she had no idea she’d be gaining four younger brothers, and she’s beyond shocked. She throws herself into getting close with her new family, but the eldest, Gen, is oddly distant. Even so, behind that cool exterior, she starts catching flashes of something gentler in him…?
