Regression? Should I read this or naah?

That debates on the person: I would 100% recommend this

if your cool with hating the seme by the end; go for it! Uke does not have a fun time!

It's no regression. Just totxic and black flags in the beginning towards the ending of season 2 it gets better and the side stories are nice. If you are the type of person who can read through toxic,abuse, and black flags then yea give it a try if not avoid it like the plague cause it gets dark.
