Well I think the demon seed thing and having to kill her brother is supposed to be important for the plot and character development for hajin. I think all that filler was supposed to make him becoming attached to his place and involvement in the world and it’s characters more natural and therefor the shock of killing him and betraying bonds he’s formed more realistic/understandable and less out of place, aka he was viewing the characters less as characters he created and more as real people who rely and trust him. Mayve it dragged on and most people didn’t like it, but if the author hadn’t established some sort of bond between him and nayoon, him killing her brother wouldn’t have as much of an effect on him. Also him becoming comfortable and complacent in being im this world and being a student etc would’ve also not made sense without the context of all the time he spent there doing normal things and making friends/relationships and him realizing how much those kids now trust and rely on him. So idk I guess u could say it’s repitive and recycled but I think that the point, like you get used to a certain daily lifestyle and before you know it ur attached and changing it is overwhelming.
Or perhaps not realistic but impactful is a better word for it lol, otherwise neither hajin or us the readers would’ve felt that bad about him having to kill her brother regardless of how objectively tragic it is (for the brother at least anyway, imagine waking up from a coma, ur little siblings all grown up, and now you have to die immediately bc some asshole grew some weird shit inside u, which is horrifying btw lmfao, and it will also ruin any good reputation you’ve built in your life as a hero, that’s actually pretty tragic tbh)
Like having to die without having your name cleared type shit, but I digress, I do think it dragged on in some ways but I do wish I got to see more of the actual school and the lessons and tests and stuff sad that it’s cut short, I also care less about the relationships and other characters tbh (which is not usual for me I typically like character heavy plots and getting to know the different characters but tbh a lot of the characters in this are kind of boring but I feel like it’s probably because they’re all just kids lol)
I've been reading this years ago. About 2-3years from it's first release and I've always been waiting for its daily releases and after re-reading the story from the bottom up to the latest, I feel like the story from 1-40 felt really good. It had a story that was flowing really good and after that it felt so bland. Everything was repetitive, and how some chapters (ranging 3-4 consecutively) are fan service. Don't get me wrong, I don't mind the fan service but having the plot delayed by it is what irks me. The romance and the misunderstanding was funny at first and I really did find it interesting, but again, having to see it oh so repetitively makes me think that the author ran out of ideas. And clearly after 100+ chapters did they only decide to return to the "Brother demon seed plot" not to mention, a random addition of the Rival character of the OG ML. It felt so forced that she was so instantly powerful and not a single background story but only a simple line explanation of who she is and what her capabilities are.
Tbh, I personally think that the author ran out of ideas on how they should continue with the plot and recycled it until they had a decent enough amount of chapters to continue on with the main plot.
