I think he revealed his plans so the ML would stop pressuring and treathning his friends. He even sent spies to watch over the Mc, so he just did that to not make the ML angry (which in fact made it worse)
it's precisely because ruth knows ail's temper. that redhead controlled all things in his hand, he doesn't even back down from threatening people around ruth. ruth just playing it safe. because no matter how much he hides everything himself, ail would know later
He's not stupid, in fact keeping it from him would be worse, bc he would learn in one way or another.
Knowing how much of a psycho this guy is why is he going on revealing his plan A-Z to this lunatic? Cant he keep things to himself? He should have just said soso instead of giving details. Stupid MC.
