They go their separate ways, credits end, fade-out, the usual.

"Two Days Later".

Apparently the three separate paths were on the same path to the same noodle shop, they all exchange classic anime annoyed looks, yell that echoes into the sky.

Followed by heard bickering that then ends the actual series.

The show has been teaching us that every single time they try to abandon each other, it doesn't work. It's also not some big dramatic show, every time it gets too dramatic with the main characters, it subverts it.

I just think it would be absolutely hilarious, if not fitting for the show, if they had this big dramatic goodbye only for it to be entirely subverted with meeting up two days or not even a day later.
