It's come to my attention that most people don't like Y/N stuttering. I think I've done this once or twice in my recent fic, so I apologise. TT.
I personally think stuttering is not something reserved only for when you're "shy" or acting "embarrassed.". It easily一and naturally一 comes up when you're flustered, eg. someone suddenly asks you something you don't have an answer for, or when you just think faster than what you were doing.
Anyway, I'm sorry for those who maybe cringe at it, but just a warning I'll probably continue doing so in my current one I'm writing. ^_________^
