우리는 조구만 존재야

Great for any level

This is half a manga, half a sort of diary. You get small stories revolving around this green dinosaur, either in the form of a couple pannels of manga, a diary/essay or both. Topics range from how to do your laundry to going to therapy and more philosophical questions (aka shower thoughts). Anything and everything really, that a regular person has probably experienced at some point. Everything is super relatable and told in a fun and interesting way.

Now, you may have already noticed what's coming next. As topics are very different, the level of writing varies a lot. Some of the vocab used can be daily beginner vocab, and some of it is extremely specific and complex. Grammar complexity similarly varies, as it's generally very simple in the manga parts, and can get pretty difficult in the written parts depending on the topic. As of writing this, I would say in a couple parts the sentence complexity and grammar points used are harder than L25 novels, but again for other parts the sentences couldn't possibly be any simpler.

When I decided to read this, the website advertising it was saying that it was something that could be useful for learners at any level. And now I absolutely agree. A beginner could read some of the manga parts, at intermediate you could read through all of it (with some not so great understanding of certain parts) and at advanced you'd still be reading an extremely entertaining book and potentially learning a few words and grammar structures as well.
