A great drama with a poor and insufficient ending

I was loving this drama until the last two episodes. I hate when the ending leaves holes in the story. What happened between Manager Ahn and his wife after they had the big fight at the company building? Did Hee Sung accepted PDNim to be the father of her baby? How did the encounter between Kim Ji Wook and his biological mother go in Canada? Did they developed the IA project to help elder people? Did Hae Young got any recognition at all for creating the successful product at Kokoa?
I'm so mad!

Good story with bad time managment

The plot is interesting but it's really complicated to be solved in just 12 episodes. The drama never reaches its climax and suddenly finishes in Ep 12 leaving some loose ends.

Wild Animal's members should had have more time to develop their characters to make the story stronger and I'd like to have the chance to see more cute moments between the main couple. Their chemistry tries to rise along the drama but fails to fully bloom

Positive side: it's an original tale plenty of comic moments. Beside the critics, it was worth the watch.
