With a probability of 99.99%, when a stunningly beautiful and incredibly well-built girl calls a guy "master," it's typically similar to what we see in those dramas.
Hmm, here we can let everyone unleash their imagination!
For instance, the guy might be someone high up the social ladder, while the girl could be a maid or an underling—or at worst, a slave—ready to devote everything for her master.
To put it simply, whatever he tells her to do, she does it!!!
But placing this scene in today's world seems weird because, after so many years of reform and opening up, these unequal things have ostensibly vanished.
However, if you must find one possibility, it could be human trafficker...
Could it be that their beloved and hated Lin Xi is actually a human trafficker???
Moreover, this girl is a Western beauty!
Her looks, even in comparison to Hollywood stars, are simply unmatched.
Such a girl calling the classmate they see every day "master" is truly shocking!
