He’s partially being cooperative because he actually needs Rian’s help to not end up in prison. We’ll see his real character when he has the upper hand again.
But he’s also genuinely crazy for Rian lol, there signs have been there in previous chapters but came to light here. Those blushes don’t lie. It’s hard to say for certain whether he sees Rian as an equal or just his favourite toy though.

Doesn't anyone else feel that Enzo's character just had a flip? Like this is a bit strange, he hasn't ever spoken this way, he never behaved this way, even just until a chapter ago he was the usual enzo and it doesn't even feel like og or that maybe his lust consumed mind is making him act this way. It just feels like inconsistency in writing.
