Alternatively, if you like the idea of graded readers but feel like the one i pointed to is still too high a level then start with this

The idea is the same is the same. Doesn't take you as far obviously but it starts from basically absolute zero and is much more conducive for beginners. The vocabulary for each story is right there in the book as well as english translations for all but the last couple stories. There's free audio as well. By the time you're done with it, you'll definitely be able to jump to the other one.
Well good luck on your journey.
I've been reading this one and it's good if you're interested in traditional folk tales: https://www.amazon.com/dp/B0796WLNBP/ref=dp-kindle-redirect?_encoding=UTF8&btkr=1
It comes with an audio disc.

It was pretty basic and easy in the beginning. As you progress towards the end, the folktale is less altered, and becomes harder and longer. It's not hard to the point that your eyes will bleed xD, I would say like above beginner to low intermediate. On top of that I repeat the audio that comes with it, so I can improve my listening comprehension. Moving on, I bought 2 kids book that were only like ~20 pages. I wouldn't recommend them tho tbh. Right now I'm beginning to read books that are 100-200 pages. Not too short and not too long. Hopefully after those, I can progress to even harder text. Reply if you have anymore questions!
I agree with the fact that it is hard for true beginners. https://www.amazon.com/Korean-Stories-Language-Learners-Downloadable-ebook/dp/B0796WLNBP/ref=zg_bs_158212011_7?_encoding=UTF8&psc=1&refRID=DE7E01CF6AVJVNJKK8T7 . And that is why I would recommend this book for true beginners, because reading it will help understand structure, but as soon as possible jump on to intermediate text, because it will boost your reading capabilities. As for grammar, I don't know how Europeans would go about teaching them a new language, but I would suspect that they wouldn't just dive into grammar. Take Luca for example, https://www.youtube.com/watch?v=_mwLvbvMho0 , he only knew Italian at the time. When he was learning English at high school, he was confused at all the grammar and tenses, that was introduced to him. It was only when he graduated, did he take English to the next level. I personally don't know what he did to get to fluent English, but I do know he preaches about reading a lot. Reading is suppose to be hard, in the beginning, cause it doesn't make sense to you. And, that's why you have to do intensive reading for a while. It's not till you're at like a high intermediate to start reading books extensively.
Yes there are a lot of contracted words that I have come across with while learning Korean for about 1 month. Like 것을 is contracted to 걸. 것이 is contracted to 게. There are many more that I want to tell you, but it's probably too advance for you to know... Also tbh I wouldn't say you have to focus on grammar books, but I recommend reading graded reading books for kids or learners. Once in a while try to look at the grammar form to understand what they mean. Also I wouldn't only focus on songs as they have slangs and they change up some of the words to make it sound nice. I'm currently on this book and I'm on the last 3 stories. I would definitely recommend it https://www.amazon.com/Korean-Stories-Language-Learners-Downloadable-ebook/dp/B0796WLNBP/ref=zg_bs_158212011_18?_encoding=UTF8&psc=1&refRID=3MHP1FR1S3K89W4JV1DC. Please read a lot of reading books and listen a lot. Practice speaking when you get comfortable. Also if you have any questions, feel free to ask. 하실 수 있으세요
