But, Norn is a normal child.
A bit different from you and Aisha.
That's why I'm sure you might feel impatient at many times, but please look at it over the long term.
Also, probably because I was spoiling her, I think she has some selfish points.
She also seems to hate you as well, along with that, her relationship with Aisha isn't very good.
Since that's the case, I think there's the possibility that she might end up being isolated, but... as an older brother I'd like for you to look after her without hating it.
