i don't know why i never thought to check this before but i need my fellow english speakers to know that not only could feng xin not think of a fake name, he couldn't even come up with different characters to use
maybe that's why nan feng and fu yao appeared to be so mad at each other when they first show up in the novel
mu qing just glaring at feng xin like "you idiot. you absolute imbecile"
"do you have a name"
".......yeah"
"what is it"
(they arrive on earth)
"n-nAN FENG"
Its SO funny that he put 南 ('nan') in front of his own name (because its a common way to not put 男 ("boy", also 'nan') in guys' names) its like:
Fx: heres my oc.... "Guy....made by me"
Fx: (accidentally names his oc "homosexual")
(Because 男风 is a slang for male homosexual)
