Chase already has problems finding temporary replacement for his security team. Or why do you think he hired Mark's team?^^ It's not just he is a problematic client, he is also a dominant alpha . (And I think he is not the most intelligent member of the family, he has not that many muscles (Josh has more musclemass than Chase) and experience with fighting.)
The regular guards of those are gammas, which are also very rare.
Certainly his father would be able to get him more guards, but Chase is on bad terms with is family, broke off contact. Although he is chipped, as all his siblings, so they always know where he is.lol
But yes, 5 against the mob are not much, but there is also security in the building.

Sometimes I can suspend my disbelief with these wattpad manhwa but I'm REALLY struggling on this one. You're telling me the most famous actor doesnt have an army of guards. It's not like most of them would interact with him much?
Sure his private security detail would hate his guts and be a constant revolving door of different teams but you're telling me FIVE GUYS is all he had to defend against a mob so rabid they may as well be zombies. His agency isnt like... shelling BIG bucks to keep their headliner safe?
I'd why this one broke me over all the other shit I've read but man I cant
