His clothes are as red as blood, and his clothes are as white as snow.

Demon Lord: Then let's change it. I will be your master's teacher.
"National Master, I intend to betroth Princess Shengye Kingdom to the crown prince, you see..."
"Your Majesty, the prince has been ordered to commit a peach blossom disaster, but his master is evil. If he accepts this peach blossom disaster, he may be in for a big disaster."
The seventeen-year-old prince said: "Master, there is no need to hide anything from me. You can deceive my father with your tricks, but you cannot deceive me."

Prince: "... Yulang."
"So good."
The ending is HE, sweet pet for three generations.
