In fictional stories normally would be hard to talk about logics. isn't it ?
@Karma ok, how to explain characters in Marvel? it's like that. And about cat memory cat has excellent memories (google it ) & they can remember their way to go back home even after long(our cat went out for 2months and came back by herself). It's hard to train a cat as they're independent but you can teach them some useful behaviours. Anyhow this is not a real world in the movie so cheer up & enjoy the show :D , ;) .
Why would they change the plot because of the age gap?
ok let me tell here :) . 아가씨 (Agassi)means young lady or Miss. Depends who want to call you . I'm 40 and a harabaji (old man/grandfather) called me in the street aggasi but other people to calling me say 저기요(Jeogyo) or my social title or depends on where I am like in shop call me 고객님(gogenim means customer) or at hospital 환자분 hwanjabun(patient) . Only very old people call younger woman aggashi or husband family to wife sister(if she is not old). Calling someone ajjuma is not polite. to around 60s or end of 50s you can call 아주머니 ajumani but not very polite so better to call "imonim" or "imo" 이모님 which meant aunt. 40 is not old :( . I still look good and fresh :D people normally think I'm just 29 :D or early 30s.
This is kind of based on the Tokyo terror attack with sarin gas (Chikatetsu Sarin Jiken) in 1995. That happened by members of the cult movement Aum Shinrikyo the organization founded by Shoko Asahara in 1984.
Although there are only 2 episodes left
