Hello, thank you for subbing this drama. 

What vpn do you use to access the website tver.jp? I am trying several ones but the episode is not loading. And how can I download the episode so that I can add your subs to it?

I use flyvpn mobile app to access TVer through mobile browsers and the app. And for computer, the tunnelbear VPN worked fine.

Hey are there subs for all the episodes or just 2-5?
