This is going to be a little complicated! First of all, do you watch on phone or on computer? Because it will be easier on the computer.
I watch on my phone using a free VPN called “FlyVPN,” setting it to Thailand. The tricky part was download an app which was not available in the USA App Store. So I had to sign out of my iCloud account, make a new iCloud account where my territory is set to Thailand, download the Viu app where this show streams, sign out of the Thailand iCloud, and sign back in to my regular iCloud.
If you watch on the computer you can get a VPN for PC browser and watch directly on the Viu website.
You can watch for free with ads but I think the quality is better with the paid version. The only regions this show is available in is Thailand, Philippines, and Hong Kong.
