Yes, that was before but things have changed when Casimero failed to show up in their supposed weigh-in with Butler a day before the main event.

Inoue won’t be taken by Casimero antics: ‘I lost interest in this guy’
This means that Inoue is also monitoring this match of Casimero and probably have been disappointed on what happened. So it's in the hands of Inoue if he gets interested again to fight Casimero.
But there's still a chance I guess if ever some good and exciting match has been shown by Casimero.
They both still inside same division and the chance of facing each other is always there,
As long as they both handle a belt, the call for the fight will remain. We don't know if how long we need to wait
it's all on the promoters side.
Casimero just need to continue winning whoever fighter that will challenge him, it's just like Pacquiao and Mayweather
the fight happened after many talks behind two camps.
I hope it will not take more time before they will fight, now tha they are both are their prime, they have to give the fans a chance to witness a great fight. I believe that Inoue will still remain as the heavy favorite to win, so there's nothing to be afraid of fighting against an underrated champion.
