Please Excuse My Younger Brothers

High school student Ito Hazui experiences a sudden and dramatic shift in her life during the spring break following her first year. When her mother remarries, she moves into a new household and takes on the name Ito Narita, hoping for a fresh start with her newly formed family. However, upon arriving at her new home, she is taken aback to discover that she has gained not just one, but four younger stepbrothers. Thrust into an unfamiliar dynamic, Ito is determined to build meaningful relationships with each member of her blended household and make their shared living situation work. While she puts her best effort into connecting with her new siblings, she faces unexpected resistance from the eldest brother, Gen. His demeanor toward her remains notably distant and cold, creating a barrier that makes integration into the family more difficult than she anticipated. Despite his aloof exterior, Gen occasionally reveals glimpses of genuine kindness beneath his guarded facade. As Ito navigates the complexities of her new role as an older sister, she must find a way to bridge the emotional gap with Gen while forging bonds with the rest of her lively stepbrothers.
