The main story was rushed, and this just continues it; two years later, the western king gets over his dissatisfaction with not being able to dominant the eastern continent and is just pleased with trade relations? Heck, maybe it's a lie, but even if it is, this is just a side story, so the time for action was earlier. Plus ML is the fourth son and we're only just now meeting his family. The author is one of those people who's good at sex and cool concepts, but not actual story execution.
