I feel that Godo isn't stable enough for a lover. He'd probably only see Kyose in the kid, and in the end kill him. No real basis for that idea, but I've read a lot, and with this style of story, it could easily happen.
He was obviously not in a good state of mind.
Suffering from at least some severe ptsd, the mask thing kinda implies he also had a head injury and his face got messed up? Not to clear on that.
So agreed, not the best way to have a relationship, constantly seeing your dead lover in your new one might push him all the way over the delicate edge he's always on.
That boy better look for that (hot mask) man who give him candy and demand him to return his pure heart. It was bitter-sweet
