What a great read

Had a bit of a slower start, but really great plot and characters/character development. You really feel yushin's journey as he slowly grows as a person and gradually finds his humanity as a fish with jihye. All of the fish knowledge was mixed in really well and you could tell the author knew what they were talking about. It was smooth and situations always made sense in how they resolved themself without reliance on plot armour/deus ex machina so that was really refreshing, especially when compared to a lot of isekai out there. The enemies were well matched for the mc, and the final boss was built up excellently, with just enough hints/foreshadowing while still keeping it interesting for the final reveal. The 4th wall break at the end was also gold lmao.
Honestly a really good read on all fronts, with a lot more depth to it than I initally anticipated considering the title lol
