I stumbled upon this by accident and was pleasantly surprised!
The feel of the movie and its premise was refreshing.
I can't say I've seen a lot of Hong Kong movies like this...

At first I was a bit sceptical about this, especially the plot and the characters age cap (Not that it's ever actually mentioned in the movie).
I was afraid this would simply end up as one of those stockholm syndrome movies but it didn't (not in my mind anyway).
The way it was filmed and the location was really beautiful and the story was in it's own way believable (except that they trained his voice that fast).
I loved how I couldn't predict Yung's train of thought or actions <3
After you've seen as many "dramas" as I have, everything ends up being quite predictable so you learn to appreciate those characters that are so normal and tender you don't know what to expect. You just zone out and watch.
I also liked the music in this and the weird scenes it brought with it.
I'm usually very sensitive to cringe worthy scenes but surprisingly I was okay with everything in this, even the weird dance thing...
The reason I gave this sort of high ratings is because I simply enjoyed this, I didn't skip or anything and I'll probably end up rewatching this again someday.

I really recommend watching this if you're bored and aren't in the mood for using your head.
I'm not calling this simple... but, yes, that's what this was...
A simple movie you can enjoy!
