yeah, it is a different story. It's just that people keep mentioning the movie and I assume that what they are referring to is the korean movie, "my wife is a gangster." but as I said, even both of them have the same name and same premise, "gangster wife and normal husband," they are still 2 completely different things.
It actually has three parts, but the last part doesn't really concern the first two movies. I haven't watched that one, but I did see the trailer... idk.. I think it would've been better if they used the same heroine. because then they could've just made a different movie.
(then again, it was a good ploy to capitalize on the popular franchise instead of hoping that a new gangster movie of the same premise would still garner the same effect as the original)

Comparing the movie to this web comic, I think that they have the same concept but the story is pretty much different.
In the movie, the wife is a hardcore tomboy who doesn't really like the husband, and was just "forced" to marry the husband because of her dying sister's wish. In this web comic, my first impression is that they liked each other..or at least the wife really tries to be a wife...
Aside from the derpy husband, the other characters are different.
The movie had more "realistic" characters, while this webcomic has a more "beautiful" cast.. ( Most of the time, I feel that having too many "beautiful" characters is overkill)
(on a side note, the movie wife had a flat chest. while this wife has big ass boobs...)
This webcomic probably doesn't have any connection with the movie because the movie is korean and this webcomic is chinese.
