I watched the trailers and thought we'd get an injured guy who required physical therapy and that he and his physical therapist would fall in love over the therapy sessions and through the healing process together.

NOPE!!!
Not even close!!

The first 10 episodes were incredibly slow and probably could have been done in 2-3 episodes maximum. Then episodes 11 and 12 were just questions upon questions upon questions that led to a whole lot of, "WTF did I just watch?"

Really, the downhill side starts at the end of episode 10 when no one explains what happened to Dr. Yang and what the photos were of and what was posted about him. I even tried using a translator to read the text given and it was a mess that made no sense. So, I have no idea what that whole bit was about.

Milk & Pun weren't even in a fully established relationship yet, but hey give them a baby and 30 seconds later fast forward 5 years later and they're a happy family of 3 in episode 11.

Toss in Pun's parents and the fact that they haven't seen him or talked to him in something like 4 years and they suddenly visit and want to have a good relationship with everyone... but we never learn why they were on bad terms to begin with.

Who is Jame and why did it feel like he was preying on both Pun and Milk when he met them separately in the last episode?

Suddenly the biological mother of their son decides she can be a good mother and she takes him back, and Milk doesn't seem to fully understand why Pun is heartbroken at losing the son he's raised for 5 years??

After all of this Pun suddenly proposed to Milk, who accepted, and everyone takes that as their wedding and yay, congrats for them!! By the way, the end!

If things had stayed slow, and mildly boring, but kept a steady theme/story through the whole thing then this would be a completely different review. However, they threw in so much WTF and the kitchen sink at the end that there's no way to redeem the last 2.5 episodes.
