I don't like how MC was less civil and more disrispectful towards his "senpai", that were rightfully pissed that 2 kids without experience got added to their team and even given command over them if they felt like.
Ths guys are risking their lives and got suddendly burdened with babystitter duty for 2 kids in a rank B or C dungeon, we know how it works, but the protagonists should understand this guys are angry at the situation.
The guys that wanted to rape the heroine got treated better, storytelling is prety bad, told it before, will continue to say it for so long as it stays like that.
