"Give me a moment to think, please," is all Koumyou says, but he doesn't let go of Devero's hand. In fact, his other comes up to cover it from the other side, too.

And he considers, now, what Devero had said just a moment ago, about 'Madame' always expecting him to be available to meet her needs. Her prerogative to decide who to 'share him' with. That he can't be trusted, even though he tries so hard... and so on.

Koumyou doesn't have any of the details, but that's still enough to make him feel a bit... ill. That's... he's no expert on how people should treat one another, not really, but...

Devero sounds like a kicked dog, and this woman sounds like she enjoys the kicking. And perhaps even more, the tail-tucked, terrified attempts to make her happy.

"...I think it's very good that she isn't on the train," he says, finally. His tone is deceptively mild, "Because I might actually get angry."

And no one wants to see that.
