I won't watch this because it's not my thing, but if you enjoyed it, let others know.

It made me curious as to how many other Korean programmes got/are getting Filipino remakes.
I'm not sure, I haven't tracked. There are Filipino dramas I've watched years ago that I had no idea was based on a K-drama or a J-drama or Thai or C-drama or Latin American. I think there are other MDL users who have a list of Filipino adaptations.
GMA, the network behind Start-Up PH, did a lot of adaptations for more than two decades now. In the K-drama adaptation, the most popular was "Descendants of the Sun", that adaptation was a huge hit, and I myself highly praise them for it.
