His name is Pressian. Ray calls him by his name for the first time in chapter 23 but it was mentioned in one of the earlier chapters.
But yeah I agree, Ray was explicitly clear about them just being lovers and him not wanting to be empress and the emperor agreed to those terms so this is just...childish.
The emperor is being dumb, since the beginning, Ray told him that he would not become the empress and he agreed, now he wants Ray to do the one thing he refused to do. Ray has a good reason for this as well, I understand that the emperor might be jealous, but it is ridiculous to expect Ray to become the empress when the emperor knew from the beginning Ray did not want to become the empress under any circumstances.
Also, does the emperor have a fucking name? I could not find it for the life of me
