Yeah, I know it was to make him have second guesses on whether Ninomae gave it,
but I'm thinking that if that part was removed from the plot of this chapter, it wouldn't really effect it so much? Since Ninomae gave him chocolates at the end.
It didn't really add anything to the story that Minai gave chocolates too him.
so it you took it out it would be:
Mom gives chocolates > Suzuki meets Ninomae at the clubroom > secret kiss of Ninomae > ending
So for me, the additional chocolates from Minai had no effect on the main progression of the storyline, that's why I'm thinking it might be a curveball of the author to hint a possible romance for Minai, even if she does technically give to all the clubmembers. We'll just have to look out for her "eye" logo in future chapters I guess
