They want money?
I actually went to the site and tried to see why it has a paywall the site said "This is an early access chapter. In order to read it, you first have to sign in and purchase the chapter using cards balance"
So I think the chapter is not supposed to be released yet or it's not due for a free release yet, hence the notif saying "early access chapter". Correct me if I'm wrong tho, since I'm using game logic as the approach.
Update to this: I actually tried logging in, and they want me to purchase said coins for $10, $20 or $30 which gives 1000, 2000 and 3000 coins. So I can say that they made the last few chapters paywalled as a means to support them and continue their work. As I did this within the hour of my first reply I am still unsure whether it will be paywalled permanently or not since it's still saying "early access chapter"

They have up to chapter 65 ( aka series finale) but 51-65 is paywalled. I’ll try to find other sites that don’t have those paywalled and include them in a follow up comment. If I’m not able to find it, it’ll just be this comment.
