I didn't quite understand this one, it was pretty confusing, Imma just assume she was a ghost girl trapped in the doll.
No, like Pekoe put under spoiler it's actually her twin sister who die before birth.In thoe kind of situation it can happen that the dead foetus is absorbed by the other one. That's what the mom mean by "Onee being a part of you", Mom was most likely gonna be birth to twins but the Onee die and get absotbed by Mii. The doll most likely represent the dead sister and Mii throw in the fire can mean she understand the situation and get over it
The obvious solution here is for Mio to intervene and bring them together for a meal.
I really wish not. I understand it's the title but i don't want Mio to do too much for Shizuku.
You don't seem to have a good reason for that though. The story clearly puts the brother in the wingman/suppoprt role, so wanting something else misses the point.
Yeah i know that but what i mean it's i want him to just give advice and not doing all the job like the festival or the amusement park. You can be a wingman without having to constantly be behind one's back.
