I've only found one ending that's ambiguous w/ Randal when you choose to side with Mavvar in the war and even that's still somewhat sad. The MC and Randal stand together while they talk about how much they both really miss and wonder where Markus is. The game had so much potential to be more and it fell flat in a few areas and I'm sad about it because I've waiting a full year along with others for this visual novel game.
