I don't know what that means, but Jill gives us a hint.
But first things first. In EP1, Stephen is wearing his wedding ring. In the intro of EP3, Stephen is still wearing his wedding ring.
Look at Jill's hands. The scene is in Stephen's office, after Chad's attack. She explicitly points to the ring finger. On Jade's hand, it is very faintly visible so she is wearing her wedding ring. But Stephen is not wearing his wedding ring. This is odd in that it's actually Jade who has the reason to take off her wedding ring, not Stephen.
I've only done a cursory search now, but I don't think Stephen wears his wedding ring at all after the EP3 intro. But instead, in EP8, he has a different ring on his ring finger when he asks Isabella out. It's a black ring.
I think so Stephen has something to do with the MC's family. I'm just writing gender studies and what Dani asks Jade while giving the MC a handjob.
