God I MISSED Being Cringe!!!! - Tumblr Posts

Ok sooo Astro boy Phantom of the Opera (kinda) au ✨

SO. Since 03 Tenma pretty much IS the Phantom (and I started shipping the old men real bad) I started cooking this

The story is that Ochan is a medic and Tenma a cientist. They're old friends, but then Tobio dies (as he does) and Tenma isolates himself and makes a pact (with a demon or spirit ig?) to trade half of his soul to bring his son back (which leaves some scars or stuff hence the mask)

The half soul is used to make a new soul for Tobio's body, restored with mechanical prosthetics by his father. But the new soul isn't Tobio. It's a new life, a new person, who just carries his memories. Tenma acts overprotective and possessive of him, hiding them from the world, so the kid eventually runs away and finds Ochanomizu, seeking help. Ochan names him "Astro" since he loves the sky and stars so much and cares for the kid.

Anyway cut to Ochan spending like 80k words knocking some sense on his problematic boyfriend's head, Tenma ruins everything then learns to value his son's life etc etc and I hope they all become a happy family the end
