I always prefer children to be girls in these, It's mostly cause boys seem to be so obnoxious in these stories ( Mostly Chinese) I kind of wish instead of a mute boy it was a mute girl but so far the Boy hasn't been bad at all.
The story itself I am enjoying though, I initially thought this was a reincarnation story so I was surprised. It even had a reincarnation start that you see from stories with reincarnation.
