A story about a "pure man" who is extremely weak on the outside but extremely strong on the inside, comes to the magical world of Harry Potter and turns into a half-aged lady, well, a half-aged lady who is relatively good at magic.
Moumai: Lao Deng, let me discuss something with you. Prices have risen recently. I want to eat more meat, so can my salary be increased?
A certain Deng: Hogwarts has not had a salary increase since the school was founded.
Moumai: Close the door and let Lao Gai go!
A certain Deng: Up!
Moumai: Lao Sa, that Slytherin brat turned into a dog to scare me. I wonder if my animagus is most afraid of dogs! Revenge me!
Moussa: I'm just a mural now. The most I can do is scare people, you know!
Moumai: Close the door and let Lao Gai go!
Moussa: I'll go!
Moumai: Lao Gai, you are really my mascot!
