Louder than Words (Quintessential Quintuplets X Male Reader)

It's been 5 years since the first day of tutoring for Fuutarou and (Y/N), Fuutarou is a know it all who always gets perfect grades but lacks common sense and has no friends. Except for one, that being (Y/N) Hoshi. (Y/N) is the opposite of Fuutarou but the one thing he lacks, he can't speak. From an accident (Y/N) lost his voice and has no way of communicating except through his actions by sign language or by phone. One day Fuutarou begs (Y/N) to help him tutor a girl he decline and accepts to help him, despite trying to find a job due to no communication he would take anything at this point. But it comes with a small catch, what he didn't know was that he would tutor not just one person, but Quintuplets. Let's see how (Y/N) interacts and helps these quintuplets from being stupid to smart by showing that his actions truly speak louder than words. (Wanna try something different, it will go the usual story but also some changes too)
