Synopsis
Uchi no Uchi no Otouto-domo ga Sumimasen follows high school student Ito, who transfers schools during her first year after her mother remarries. As if that wasn’t difficult enough for the kawaii student, with the move Ito also gains four stepbrothers! But instead of going, “What are you doing, step-bro?” Ito quickly tries to bond with her new family. Or at least she tries, as she can’t seem to figure out the Narita family’s eldest son.
But while Gen Narita might have Kashiwada’s poker face, as Ito spends more time with him, she starts to see his loving soul.
