Infinite Transmigration: I'm Stuck Repeatedly Playing the Live-In Son-in-Law

Why do other people who transmigrate either become the protagonist or a supervillain, while I end up living off a woman every single time? A live-in son-in-law? I never get the good roles, and one secret identity after another gets exposed. Whether it's a low-martial, mid-martial, high-martial, or mythical world, I have no parents from the start. I'm born to be a useless son-in-law to the heroine. I get shot to pieces in the Special Forces world and weep blood in the martial arts world. Whether it's fantasy or science fiction, all I can do is meekly live off a woman. Living off a woman is great, living off a woman is sweet, and it doesn't give me sores.
