Hello! Hope this helps!
https://lilyonthevalley.com/chapter/siwall-ch-1/
I forgot to add that the extras can be seen in the drop down menu in the site TT
Thank you!! I've never used this site before, does every chapter just cost 1 lilypod to unlock?
Not at all! Their system is similar to webnovel sites where each chapter will eventually be free on the given schedule. So buying lilypods is not at all a requirement - it's just if you want to read it in advance.
It's a great if all you want to read are just the extras, they cost only 5 lilypods each,
anyone by any chance know where to read the novel's side stories? its OK if its in korean T_T but i couldnt find them anywhere
