Mom, I’ll be waiting for you in hell

A son abandoned for twenty years was brought back to his rich family—only to have his mother and adopted son gouge out his eyes and steal his marrow, with his mother sneering, "What is he?" Rescued by his grandfather, he was given a bio-electronic eye and became the heart of artificial organ research. In the end, his mother killed herself, his fiancée bled out, and the adopted son and lover died horribly. He and his father donated the fortune and traveled the world together.
