So it's good to hear that Inoue is still interested on the fight and should give Marlon what he deserves in the negotiating table. Maybe just enough for Marlon and his camp and be satisfied of the pay check that the Inoue camp is offering.
Inoue's camp is just trying to delay the negotiations a bit, as they know Tapales would be willing to fight if the price is right. Tapales was the underdog when he won the championship, so it's obvious that he is not a popular boxer. However, since he has become a champion, which Inoue is very interested in due to the opportunity to get his belts, that's why he's standing firm with his demands. It's a good thing that there's now some hope of it happening.
Inoue's goal is to unify and then move to another weight class to unify again. He is already 30 which means time is of the essence for him and if Tapales wants to make a ton of money he definitely needs to raise his cut. It's a one-time opportunity for him as this kind will not come again.
Tapales has skills but it's no match to Inoue. But he is more interested in making a record. He had to keep moving up and get as much belt as possible until he reached the size where he won't be able to resist a punch coming from someone from a heavier class.
