you mean the plot or the comment saction? (≧∀≦)
Honestly both ╮(￣▽￣)╭
Seeing how I just finished binge-reading this, I'll give it a shot.
After Diesel was spotted in an online pic, men came after both him and Ein so there's a flashback to explain why. Ein was an undercover agent working under the umbrella of Interpol Germany (in this case, he was an informant within crime syndicate that's involved in drug smuggling). Yanek is/was the son of the leader of that organization and apparently at some point Ein killed him. The men from the crime syndicate are looking for revenge. Ein was sent into hiding afterwards and he secretly brought Diesel with him since they are also looking for him (but they don't know he's a werewolf). Minsuk & Bexan's association with Ein & Diesel now also puts them in danger.
And the chihuahua is just this really cool guy whose sister happens to run a badass security company, so there's that about to be thrown into the mix.
As for the comment section... who tf knows?
