Maybe their hearing is bad lol. But tbh there is possibilty that Kanade was made fun off because he likes to dress this way so he decided to speak more femmine or smh. It might be far fetched but that would explain why she doesnt recognize his voice.
Its also possible that they just have a not really unique voices and I think its probably the right guess
I'm guessing they speak differently during and off work. Your pitch and tone might go higher using formal speech and lower during casual
I mean, if I was either one of them, even if their voice sounded familiar I'd probably disregard it. I wouldn't expect my respectable coworker to be who the other is seeing in front of each other on their off times
probably his voice not that high like some other guy who have husky voices,i know because im one of the guy who have a very feminine voice and people thought that im a tomboy
Super cute and all but how come they don’t recognize eachother by voice?
