The point here is that everything was Gift's own fault, and his friends were pissed that they did all those things for him and yet he still lied about how everything began, keeping the truth to himself until all the drama ended up escalating way too far. Glasses and Kokomi's biggest disappointment was that this whole thing is not just Kadomi making shit up and exaggerating everything, but Gift did do something that triggered Kadomi's revenge autism, and that he would even lie about something so insignificant to them in the first place.
