Hentai flat chest manga often focuses on exaggerated and fetishized depictions of characters with small chests, sometimes featuring explicit and adult-oriented content.
Well, generally speaking, if it's a visual novel about 'big chest vs flat chest' in a non - inappropriate way, it could be exploring concepts like body image, self - acceptance, and the different experiences or stereotypes associated with different body types in a fictional story world. Maybe it shows characters with these different body types interacting and dealing with various situations, but again, this is all just guesswork.
I would say no. The title alone implies a comparison based on body parts which is not a concept that is typically considered appropriate for all ages. There could be elements of objectification or inappropriate content within the visual novel that would make it unsuitable for younger viewers or those who prefer more family - friendly media.
Most manga don't focus on a girl's chest size to judge her. It's more about the character's personality, story, and development. So, no, being flat-chested isn't a negative trait in the majority of manga.
I recommend "The Secret of a Model's Wife." The female lead was a print model. She looked ordinary, had a flat figure, and had a small butt. The story described the relationship between a young reporter and a beautiful model. I hope you like this fairy's recommendation. Muah ~😗
