Speculation on why Hwang Hee-chan failed to fulfill the contract with the chauffeur service

‌I am a wealthy person who picks and chooses supercars
and changes them frequently.
In reality, that is what I want to be,
but I want others to perceive the cars as mine.
However, I don't want it to be obvious that they are rented.
So, when I drive a supercar, I want people to believe
that I actually bought it with my own money.
If I post about the rental chauffeur service—which is part of my contract—on social media,
I'm embarrassed that people might find out
that all the cars I've driven so far
don't actually belong to me.
Summary
It seems he didn't post the company's promotional content on Instagram
because of his desire to maintain appearances.
