oh Ishigami said something nice for once (nope if he said something nice too in the previous chapter that didn't happen as i already erassed it from my memory)
@Greyvenn It's a little confusing, yes, but basically what's explained here is that due to Iino's stage fright, the results of the audience laughing at her would have happened anyway. Ishigami wants Shirogane to win by a landslide so that Iino's poor performance wouldn't become a main topic of the school. If Shirogane's performs averagely, then Iino would likely become a talking point among the students and further her humiliation.
