https://comic.pixiv.net/store/variants/1tfhpynad (2nd Vol) - u may read a few pages but to read full vol, you need to buy it.
https://www.pixiv.net/en/artworks/118636772 (extra ch on 2nd vol book) - I just found the author's page on Pixiv and you may as well check this out (。•ᴗ-)✧
Found this on Pixiv and after reading the 1st ch here, I realize that it was the 2nd vol that I found there. Great to know it has 2 vol ٩(๑❛ᴗ❛๑)۶
