Something is definitely wrong with this story but I don't know what. This boy is acting a bit like a child tempted by candy. Although in this case sweets = meat. At the beginning, he acted innocently as if he completely didn't understand what was happening and in what direction it was going. I read a lot of stories with the relationship between the student - an older person but this one has something particularly disturbing about it.
My main question after reading this manga is - what kind of parents would leave a five-year-old child alone in a playground while they are at work? Alone and without a guardian. And why did author present it as if it were normal. It's crazy.
And it is obvious that author doesn't know any five-year-old child. Children at this age cannot even tie their own shoelaces and don't remember to drink water or eat. It's completely unrealistic for a child to be alone in a playground for half a day while parents are at work.
in countries like Japan elementary kids travel alone to places like school or nearby mart. The country is pretty safe and kids are taught to be independent so something like this is pretty common in japanese mangas ... Not sure about korea tho
korea is the same. children travel alone from very young ages because public transportation is accessible and safe. the technology there is also very abundant and there's cameras everywhere. and usually playground are in front of large apartment complexes with a lot of people.
but 5 years old is still quite young
