A person with superpowers in interstellar space travels through the 70s, mindless cheating, Mary Suwen
The wormhole traversal failed and I randomly fell into the legendary era of scarcity of supplies! I picked up a man for nothing, just a lazy, greedy and slippery man. I also hooked up with the in-laws who can never hold a bowl of water evenly. I thought it was a disaster... But the man turned out to be a loyal dog? Are your parents-in-law obsessed with her bowl of water?
The female protagonist is cheating, the male protagonist is just a cheat, please be careful if you mind.
