Hmm, both of the JPN and NA trailers show us about the new Newlywed Story Mode (looks like it'd be something resembling 3oT's post marriage event?) that will be added in the Switch version...But in the JPN vers, they also showed more options: Story, Another Episode, Voice Comments and Online Manual.

That first 'Tale/Story' option is definitely the main plot, Manual is self explanatory and I guess that 'Voice Comments' section will be the VAs/Producer comments maybe...

That 'Another Episode' option though....It really makes me super curious and I am crossing my fingers that it'll be something like backstory or more RF world/lore related stuff 🤔
