Hiiiii, for anyone asking on how to watch this through the official TVer link, I had the same issue at the start until I finessed a way to do it. This works best if you're using a chrome browser through a PC/laptop.

1. Download this free VPN chrome extension called Bright VPN. It'll ask you to install and set up the official app in order for the extension to work, so you need to follow along. Here's the chrome extenion link --> https://chromewebstore.google.com/detail/bright-vpn-secure-private/fbffombkfihfokifmkihbddiafipndnb
2.  Once the app is set up and you're able to see the extenion icon in the top rightcorner of your extensions menu, click on it and choose the Japan location and then click on the toggle to turn the VPN on.
3. Once it says that the VPN is connected to Japan, you're good to access the TVer link through here --> https://tver.jp/series/sriccbvyov. It'll ask you to put in some info like your post code (has to be japanese) and D.O.B. I just searched up a random Osaka post code (5300001) and inputted it in with my DOB. You only need to do this at the start, it won't ask you to input this info again after that. 
4. If you're wondering about the subtitles, I'm just making do with the auto translated captions for now, the translation is super dodgy but I can roughly understand them because I've trained myself over the years with all the japanese media I consumed to understand it.
   
   Obviously, you can choose to wait for the fan subs on unofficial sites if you like, but I personally think it's always best to go through official channels to support the people who made the show. If you have any questions, please let me know... happy watching folks!! 🥰
