The episodes in the 3 Netflix parts are numbered continuously (1 to 8, 9 to 16, 17 to 24). This confirm that the 3 parts constitute one single season.

I'm sorry, I forgot to transfer the images when I have transferred the episodes. Feel free to reupload them.

In Taiwan, the three parts are considered as three seasons. They shouldn't be merged into one season.

why the guest stars I added in the 9th to 19th episodes are gone?

Do you have an official proof ?

Because I forgot to transfer them, sorry.

Netflix just shows "3 seasons" on their open page: https://i.imgur.com/5yXanSD.png

part ("部" in Chinese) and season ("季" in Chinese) are both used by the official facebook

it more like "Trilogy" ("三部曲" in Chinese)

but you thought it as one season, that's OK

For cast list (just shown main casts), I removed the guest stars in the 1st to 8th episodes. I don't want to waste my time to add again.
