That open ended ending was indeed scripted that way for a reason...
Here come the spoilers if you have not seen episode six.

The perfect fiancé is not ordering dinner! He is ordering a hit on Angie ! There goes the bride!
Not a sweetheart after all! ( Enter communal sigh here.)

And her dad who was pretty nice and low-key as far as triad bosses go , will show just how bad-ass he can be
when he has to protect Angie and her crush. Forget about his ties to future son-in-law’s triad dad. This could get ugly or funny!

I really enjoyed this different type of drama and fell in like with Jasper Liu. December cannot come soon enough! Mind you I will have to rematch season one for continuity’s sake.
