Personally, I really like it. I can understand some of the criticism, especially when it comes to the whole flashback arc, but there are far worse manhwas out there dealing with ra**, sexual violence, and other problematic topics, and nobody seems to make a big deal out of them.
I'm genuinely invested in this story. Sure, it has its flaws, but the plot is interesting and I like the characters, so I don't see any reason not to stick with it until the end.

Does anybody know when we will get the fourth season ?
I didn't see ant news so far, and it's a shame that it ended like this...
