No worries pretty easy mistake to make!
Season one and two are all pretty much a continuous plot arc and have more consistent art style. Season three definitely has a different focus and tone. lots of people have complained about the art style and new plot.
The art in more recent chapters has essentially reverted to the original style, but the writing is still questionable (see ppls comments complaining about the raws). I’m still probably going to read, but dropping the series now is very reasonable
I personally preferred the writing and plot progression in the first 2 seasons. I'm wary whenever series keep going on and seem to revert back to using rape as a plot point ever since Pearl Boy. Personally for me, Pearl Boy went on way longer than it should have and is only beloved because of the art. It started with an interesting concept but it just kept going back to using rape as a plot device. I really hope this series doesn't go down that route as it started with a really interesting concept with the ml having an interesting moral compass one might say. I hope it stays strong for you and others who continue reading :)
So I sat down and read all of season 1 in one sitting when season 2 had dropped the first chapter. I really liked season 1 but the sudden art change felt a lil jarring so I was going to let more chapters release before reading again BUT I think I'm not going to pick it back up. From what everyone is saying, it seems the writing of season 2 has just gone downhill so much which is really disappointing but ah well nothing you can do. I hope it gets better for everyone who continues on.
