(There are private facilities, there are private facilities! Those with mysophobia should beware!) Traveling into the world of Demon Slayer and being picked up by a tough-headed boy, how should a defenseless girl with amnesia survive? Being confessed by Li Mang? Being manipulated by an "unscrupulous" lady again? ! She looks so cute, what can I do? Since I can't resist, just enjoy it! Life is hard to get by, so Yan Ying comes to perform. I can only live by eating ramen and selling charcoal! Until suddenly one day, a man claiming to be the ancestor of ghosts suddenly came to the door. The gears of fate began to turn...
