I use Private Internet Access and often get lucky tunneling through various US and CA servers. Just as often get unlucky and have to wait though.
Like you I only touch Mega for VN stuff. Cant justify the sub.
I suggest Burn for Me, which was the book recommended to me by one of my female friends. It's written by a couple, native Russian wife and a husband who used to be a former communications sergeant in the U.S. Army. The setting is a bit sci-fi and the plotline revolves around chasing a dangerous superhuman in a world where superhumans with magic exist.
I will warn you though, that the characters have an mildly antagonistic relationship to start and that the first book is much like Jill in season 1 of BADIK, much of the romantic development doesn't begin to pick up until the second book.
An alternative is to use a VPN. I use ProtonVPN that allows “medium” download speeds on their free version. I switched it on to bypass the cap and then switched it off and the download continued, but at my home internet speed which were faster than the VPN server speed.
