Reviews mentioned that it is a fans translation, check the book before buying it. Because this could be copyright infringement, and the authors should know or at least Munpia
time loop stories are rather similar, altho i dont know many, especially translated ones.
a western one that i loved & thats popular is called 'mother of learning' by nobody103 & you can find it on royal road and kindle unlimited. the MC repeats the same few weeks for probably hundreds of times, and while he doesnt have nearly as much regression depression as YJH, he has plenty lol
there are plenty of western novels that are similar to webnovels & you can find them on r/progressionfantasy, r/litrpg or even on r/fantasy
one of the most recommended series is cradle by will wight, which is heavily based on chinese xianxia novels, but its still very fun to read & i think the best way to transition back to western novels
also, nothings stopping you from reading officially published & translated korean novels! there are a lot of lists online for foreign books that you can buy in print or as an ebook, or even find for free on kindle unlimited & a library
you could try reading western webnovels too if you like the episodic storytelling. royalroad.com is the biggest site for them, but even webnovel.com has plenty & there are other sites, or the aughors have their own. 'mother of learning' on royalroad is hugely recommended & worm is another famous one from a few years ago too
