I know this may sound rude but

I had the exact same thought, like……part of this could have been avoided

(not trying to victim blame tho)

its much safer with broom, but idk why he was so dumb.

The chain is also broken you know. In chap 5 page 33

I think it broke bc the dog got agitated when he came near? Notice how it was 't acting like that when he was cleaning the poo. But anyway, like what the other commenter said, we're not blaming the victim. The uke is still the one who's mainly at fault here. Just trying to air out these questions◉‿◉

Yeah i know we Didnt try blame the victim. Its just my thought that even though he use the broom i think the dog will also feel treathen and agigated. And the result will be same since the chain didnt strong enough so it broken

I think they meant to say that, while yes, he was dumb not to use the broom, it wouldn't have mattered if the way the broom was viewed by the dog as being a threatening action & object. It would have attacked the broom, but won't be able to reach the person trying to get the artifact. However, while the distance would have been further, if the dog had been trained (as someone has said) or is a vicious dog, as soon as the chain breaks JunSeo would have to react quickly enough to retrieve the key (grab it from the ground) AND run away. Imagine how difficult it is to sweep a key with a broom through the grass, assuming you're able to get it on the first try, to the exact place or vicinity to be able to grab it. Yes, there's a chance that the dog would not have viewed this action as threatening as a person who approaches at a closer distance, but as far as I know, vicious dogs are vicious and they're already barking at you a mile away. Anyways, if we assume it views the broomstick movement as "less threatening" then it wouldn't have reacted as violently. But let's say that isn't the case, or even if it were, and the dog viewed it to be threatening enough to break free of its chains, then the likelihood of JunSeo's not being bitten relies on how fast he can grab the key AND how fast he can outrun the dog, which depends on both his speed and reaction time, as well as the dog's speed, EVEN with the help of the broomstick.

That's a nice perspective. Thanks for that (◔‿◔)

Um u might misunderstood this but I'm not being sarcastic huhu. It's actually nice to converse to people with different opinions than mine hihi
