The novel (the real author) doesn't have this dialogue, idk about the manhua (or maybe it's just mistranslation)
hello! wanted to add my 2 cents as a chinese speaker, the phrase 怪你脸黑 directly translated does mean "blame your face for being black" but it actually means "its your fault for being in a bad mood". its a figure of speech in the chinese language and isnt inherently racist. in fact, the language commonly uses color to describe emotions, like red is used for anger/embarrassment, white is used for fear etc. hope this clarifies!ヾ(❀╹◡╹)ﾉ~
Ah thank you for the clarification (╥﹏╥)♡ so bad mood as in black mood? That clears it
Author the racism ain't it
