Draw Cards, Get a Demon King

When Lu Yaoyao woke up one morning, a gacha pool connected to another world had appeared in her bathroom. A literal gacha pool, the kind that leaks water. To keep her neighbors from complaining, Lu Yaoyao has to pull once a day to reduce the water level. Man-eating mermaids, assassin elves, short-tempered dwarves... The creatures from the other world she draws are all kinds of strange. Luckily, they disappear after a one-day cooldown. Until one day, she draws a man who doesn't disappear. Lu Yaoyao: I really can't afford to take care of a big shot like you. Please quick-transmigrate back, thanks. Nan Xing: You were the one who drew me back to my original world. Do you think it was easy for me to make something of myself in another world? I don't care. You're responsible for me now. Lu Yaoyao: How am I supposed to be responsible for you??? Nan Xing: It's simple. Just marry me :) Completed works: A story about a crazy guy who wants to toy with the male lead's heart A story about a pervert who wants to dig out the female lead's eyes A story about going back ten years to raise a loyal puppy of a male lead A collection of strange happenings in an ordinary (crossed out) ice cream shop A story about a mental patient and a stone-faced patient battling wits Coming next: Pay back every grudge and settle every score.
