Alternate #2: The Face in the Mirror (Patreon)

A young man is haunted by a face he sees in the mirror, until one day, she breaks out, forcing him into the mirror as she tries to live out her life. But the man finds that whenever she looks into a mirror, he can break through and regain control, creating a forceful cycle.

Still a fairly rough idea, but one that might be fun to play with perhaps later into next year but maybe 2025 after I flesh it out some more.
