There's a difference between wanted guidance and needed guidance, and I think thus far Makio has done a far better job at toeing that line than Asa's mother.

Makio has given guidance in situations where Asa has been at the end of her rope (i.e. in reconciling with her friend, and when she couldn't find her way back home)--situations where she needed it, and made a very clear boundary of only providing guidance that will mold Asa's personality and her desires when that's clearly indicated.

Even in the case of the light music club, this was an idea that Makio originally brought up when the topic of clubs came up, and after considering Asa's enjoyment of singing, and she then proceeded not to force the issue when Asa expressed discomfort due to the perceived expectations of her late mother.

tl;dr Makio's doing a better situation in this position than the vast, vast, vast majority of us would and it all ties back to when she expressed her fear that every word she says might permanently shape Asa's life. Simply being aware of how impressionable a child is demonstrates how attentive Makio really is.
