I check at Novel Updates website and I saw that the novel already has an official licensed translation. You can find it at Amazon or any online shopping sites if it's available, both paperback and digital. Maybe even at your local bookstores?
But for the uh...freedom version, you can just look at any of those suspicious site. N0v3lhall is usually my to go site for "free" novels. Though, as per usual it does comes with the sus ads, but hey, freedom. I'll give you the link:

If you like it, don't forget to support the author by buying official works!
Can someone send me a link of this novellllll. I tried searching it on Google but the links leads to Tumblr and anywhere else it's seems all suspicious and I found a kinda reliable website but idk how it works
