In some yaoi manga, the theme of someone wanting to be pregnant could be tied to emotional growth or a desire for a different kind of connection. It's not very common, but when it happens, it usually adds an interesting twist to the story.
I'm not sure exactly. Maybe it's one that features a complex relationship with Endou at the center.
Well, some yaoi manga might incorporate toys in a romantic or playful context. Maybe it's used to enhance the interaction between the characters.
I think one example could be a manga where the main characters use origami to express their love or communicate secretly.
Some yaoi manga with kidnapping themes might focus on power dynamics and the development of a complex relationship between the captor and the captive.

Such yaoi manga is inappropriate and unethical. It's not something that should be promoted or discussed positively.
Often, yaoi manga with a strong boy might feature him protecting his love interest or facing internal conflicts related to his strength and emotions.

Well, there are some yaoi manga that incorporate zodiac animals as symbolic elements or as characters with related traits. It depends on the author's creativity and the theme of the story.
