There seems to be more. But I'm not too familiar with the language to know how to navigte that blog site.
It's not that complicated at all. If you were to go to the source link and scroll down, you'll find it links to the previous comic ("< 比起這片星河，妳的雙眼更加美麗動人。") and to the following one ("只有你能讓我心醉神迷。>"). Additionally, "Comic" and "星期六的情話" (the Chinese name of the comic) are tags on the website, and accessing either just gives you an extended list of posts from newest to oldest (going from left, to right, and back to left on the next row), with a page select on the bottom to go through the backlog of comics.
At the time of writing this comment, for the "星期六的情話" tag, we are exactly 10 pages behind (this comic is the first on the 11th page), and each seems to have 10 posts each, so we are, at max, 100 comics behind - though this isn't accounting for posts that aren't necessarily comics, and some posts can have an extra comic alongside the main one.
