This story really going downhill and it's hella disappointing. I really enjoyed it at first but then main girl dampened it but I'm used to shitty main girls so even if they piss me off I can continue the story if it's good enough... But the writing isn't good enough anymore. Plot conveniences, power of friendship bs, I felt nothing for the death of the old guy as we didn't have enough time to grow onto him or feel bad for everyone because the characters themselves didn't have time to connect with him.
And why would they make this new student a successor? The floor master is dead, and only the students survived, and there's no proof of anything that happened outside of word of said students. For all they know, he could've been an incredibly strong fella or got help from other strong fellas, killed him, made up a report, and came back. Also why hide the betrayal? It's literally CRUCIAL information! There could be other traitors in there and it's important to spread awareness!
