ending *spoilers*

initially Tim thought the SMS was sent by the doctor as the doc stormed out of the room. But as the ending revealed, the doc does not know how to use chinese in SMS. At this point Tim realizes that the real culprit is his wife.

Why did his wife go through all the trouble to catch them red handed and at the end inform tim? My guess was there was too much at stake if the men were caught red handed, not only would one relationship be broken, the other three would follow. So basically Tim's wife was just doing a cat and mouse chase not intending to kill but to warn Tim. Well im not married so i have no idea how married couples think.

yeah and that taiwan boy broke up with his girl cuz she aint giving him enough respect.

I don't think any of them break up with their girlfriends/wives. But the doctor probably finds out that he doesn't want to do it anymore, because his wife loves him so much, and he her.

Basically, it's a really dark comedy, with the wife who is behind the operation. She allows the men to think that they are able to get away with cheating, but stops them before they actually complete the act.

As the previous poster said above, it's all a game that the wife feels the need to perpetuate. A darker connotation is probably that we all need a certain amount of lying and pretending to make a relationship work, and that the wife chooses to continue playing.

"I don't know about what happened. . . because once you start writing, it all becomes fiction."

The fat guy's wife sent the SMS because she knew if she caught her husband cheating on her, she got to divorce. She knew her husband was going to cheat on her and she did not want to divorce, but she cannot act like nothing happen and stop hunting them. So she sent the SMS to make the husband team to stop their cheating plan.

no one breaks up since it's all setup by wives.

go check out the sequel to see the wives trying to cheat on guys.
