Just checked the walkthrough, there are 3 separate situations when you can get a game-over.
The first is if you let Jaye drown and the last is in the fight at the end when you need one of these to survive: agreed to learn defensive techniques from Tanaka or got Jaye's back with Christian. Not sure about the second, the conditions are more complicated.
Anyway, maybe a retcon in an older chapter is plausible. But one in the most recent chapter? Something doesn't add up. And it's definitely not chef Tanaka's spare change
