Oh, this is worth noting...
So you know that scene in the bathroom where Kyo is talking with the Imaginary Kyo based on the Kimi-iro Octave male lead? When they talk about reintroducing himself to Anna's parents (specifically Sanae), there's a little visual, and the details are hard to see, but... uh... pretty sure Anna's supposed to be pregnant. It's made more explicit in the anime, where Kyo and Anna are even dressed in wedding white, and Anna is
extremely pregnant.
Here..
The scene in the manga, the scene in the anime. Anna is holding her hand over her stomach, which might be a gesture towards Kyo, but it might be to do what the anime made blatantly clear: Kyo would totally make Anna a mother arguably before she'd even be a wife.
