Isn't otoko no ko one of the translated tags?

Didn’t see it and the commentary suggested the opposite.

I'm confused. Why there is a yaoi tag, when the girl has small breasts.

The artist tagged it as otoko no ko.

This happens to every human, both males and females.

I'm not arguing against that it's a male up there, just stating my observations.
