I think that in the story the pervy ones are the bad guys and the "good ppl" are the ones that adopt and treat as regular humans.
Yes they treat them as human but still harass them I know it's just a manga It don't give nice ideas like it's okay to do things to children as long you treat them well ? The right stuff was to take them to an establishment feeding them educating them ..... not adopted as sex partners
They do take them to be educated - hence the smiling child being adopted by parents and the adoption day scene. Just that the ppl we followed didn't do that But I do agree it'd be nice the see Sui go and come back and a normal human and then choose Angie
The story is kinda of dark like ok they save "children" from pervs and resell them as adoption ? To other who do pervy things to them but kindly ? Like isn't this pure manipulation ?
