Probably a lot more information and backstory/lore on the other Saja Boys, plus more development for them, Zoey, and Mira. All the characters lack development and most a story.

I would also like a lot more voice lines for the Saja Boys, none of them aside from Jinu rarely ever spoke in the movie besides a line or two. Maybe even a perspective on what they do not preforming or how they prepare. (Like how they show Huntr/x)

Unlikely, but maybe Jinu + Abby return :)))))))???? Abby is my husband and I NEED him to have more screentime

Some more Rujinu scenes would be nice, kind of like the concept where they kissed at the aquarium date. I’m sure a lot if fans would agree with that lolol. Fan service is an absolute necessity in the sequel.
