Looking for a Quick Transmigration Harem Story Where the Male Lead in Each World Is Part of the Supreme God

One of the mini-worlds is set during the apocalypse. The opening goes something like this: the female lead is thrown out of the base by the world's original heroine, who uses the original male lead's name as an excuse. She's hiding behind a sofa in a house when the male lead finds her and falls in love at first sight. I'm out of characters, please help! There's another mini-world that's an infinite-flow setting.
