the love interests do have the anatomy of children, and that would be the same even if they had bigger chests. they are short, without curves, skinny, etc. they look like children. it is not just the flat chests that make them that way.

I understand your concern, but I do not agree with that assessment. The characters are designed as stylized, anime-inspired adults. A shorter height, slimmer body type, or less curvy silhouette does not automatically make a character childlike or underage.
I respect that visual design can be interpreted differently, but the characters were not intended to be read as children. All love interests in the project are adults.
