Nezumi was trying to hold back her laugh/smile. She didn't think it was appropriate after she tried to kill Ao, but Ao kept praising her over and over, so she was apologizing more to herself than anything.Sorry what did she mean her mouth is doing it on its own?
I wonder by that too. Such as what happened to Ao during his childhood when his sister diedi wonder if we would've gotten a conflicted arc/flashback about his sister if the Peter thing didn't make the story even more wild/off the rails
Thanks for explaining! And scanningNezumi was trying to hold back her laugh/smile. She didn't think it was appropriate after she tried to kill Ao, but Ao kept praising her over and over, so she was apologizing more to herself than anything.
