[Abandoned Snake Woman of the Demon Clan] × [Overbearing, possessive, volatile, obsessive King of the Netherworld]
“My daughter, it’s not that your mother doesn’t want you. You were born unable to cultivate demonic power. Once you enter this River of Forgetfulness, it splits in two: one branch leads to the Netherworld, the other to the Demon Realm. You’ll die if you go to the Netherworld, but the Demon Realm offers a slim chance of survival. Your fate is in your hands.”
“King of the Netherworld, a baby girl has drifted down the Nether River.” [The speaker sounded like a corpse.]
“Are you all useless? Just kill her. Why are you asking me about something like this?”
“But, Your Majesty, you said to kill only those from the Divine Clan. The one who drifted here today is from the Demon Clan.”
King of the Netherworld: “She’s my wife.”
Everyone: “Huh?”
If you don't laugh after reading this book, I lose.
Although the male and female protagonists look a bit like children, they are very old, and they are even more impressive the more they look at them.
