Posting Comments in Pages

After a quick search of trying to find out how to enable comments on pages, I’ve determined that the problem lay in my theme. As a complete php noob, I have no idea what I should do with the theme’s code in order to make myself a functioning page with a proper comments section. Please help!
This is my site, by the way– I’m trying to create comments here: https://seonbinovels.com/projects/king-shura/king-shura-prologue/
