If you want PAKAPAKA's work, then you only need to complete the following steps.
First, open the Pixiv page and bookmark the works you want to see.
The second step is to click the button next to "Follow," then click "Request Friend" (I don't know how it works in English mode, but it's for good pixiv friends).
My pixiv,It's this
Third, send him a private message and request to become friends. It's recommended to translate your request into Chinese, be sincere, and express your strong desire for his work (if you can't even do this, it means you don't really want it that much, right?). Remember to emphasize that you've already saved his work to your favorites. He doesn't care if you've saved it or liked it; as long as your attitude is there, he'll open it to you.
In any case, he was sharing his work for free and didn't set up a paywall.So don't find it troublesome; it's because he was previously subjected to unwarranted abuse.
One more thing, after becoming his friend, don't forget to click "favorite" when saving his work.
You just need to click the heart.
