I'm just gonna go ahead and awkwardly ramble about my random ideas of being able to romance a Micro.
What if you dated a Micro and had the ability to devour them with oral anal and cock vore, but instead of doing QTEs to not get digested, you have to do them to resist digesting the prey. And much like with Syd, you could at one point have a conversation with them where you tell them they'll get digested next time you eat them.
And if you do digest them, you can either leave it be, to make it permanent, or click on the Belial statue to have them return with no memories of what happened (same would go for Melo of course).
Thanks for reading if you did.
