Supporting Characters Survive in Another World

A strange man breaks into the house, is he actually a god? Reincarnated in another world, but ended up playing a supporting role? There is a beautiful maid, but a cold-tongued woman? God gave you a superpower: watch other people go around? Is it Lu Ren, a social animal, or Su Zimo, a down-and-out nobleman? Is he a supporting role in the script of The Proud Man, or is he the protagonist of his own story? Maybe the answer lies only in your own hands.
