@Ianes Grécia yes, this situation has nothing to do with it. The bodyguard should be trained enough in hand to hand combat to be called a "pro". So why is he going down like a cannon fodder??? Having your guard up even while attacking and not overextending are literally the most important parts of fighting, so why is his first ever attack disregarding both of these? He's charging in like he drank two bottles of vodka and like its the first time he's in a fight. What I'm saying is that just experience doesn't justify this situation, if you're gonna make him this pathetic then don't even call him a pro in the first place, he has no difference than a person with zero combat training.
I absolutely refuse to read yaoi or yuri and I hate bad translations. At least show some effort and write your translations in english.
