I always assumed Eurydice was Heejae's former assistant who he clearly loved but didn't know how to articulate. The way he sees him as a ghost whenever the past repeats itself feels very apt. Whenever he reverts to his stubborn, dismissive ways, Heejae is Orpheus looking back, grasping for reassurance that doesn't exist, in a way that will only harm both parties. "No More Eurydice" echoes this idea that, at last, Heejae has to find a way to stop leaving Eurydice's in his wake aka repeating the same behaviour, but also that Garam (eventually) won't be a person characterised only by the lover that left them (even if they end up together again!)
