Pus, the son of the Demon King, is a diligent and inspirational heir who promotes the Demon Clan.
The Demon King would say in his ears every day, "Only you can revitalize the Demon Clan."
He was convinced.
To become a qualified heir, you still need to pass theoretical knowledge.
In short, to strengthen knowledge, you need to write homework.
This became the biggest source of trouble for eight-year-old Pus.
Just when he was biting the pen holder and not knowing how to write, a girl's voice came from behind, "Idiot, there are three types of demons, animal form, humanoid, half-human and half-animal. You can't even do such a simple thing!"

Princess Lulu has not wanted to be the emperor since she was a child, but she is extremely talented and has a very good memory, and she can read everything.
The most important thing is that the Queen Mother only has one daughter.
Her greatest pleasure in the palace was to use magic to cause trouble and watch the maids in the palace being at a loss.
Recently, she found a new fun. Every night she would go to the house of an idiot on Pulus Continent and watch him write his homework until he collapsed.
The bad little princess only helps after seeing enough, but every time she is thanked by the other party, which makes her very embarrassed.
Until one day, she found out that this man was actually the son of the Demon King? !
Motto: Hard work will pay off.
