I also have been marinating my thought in plot spices for Therapy Playlist (Ikuzo, Temera!) to give it a good ending with domestic established relationship chapters (courtesy to canon soft Sukuna in JJK ending) because I honestly don't see the urgency and importance for bad ending for this fic. And I'm not one to give bad ending without solid reason just because I can like oh danger=conflict=dead=good bye. There's no major wrongdoings in Sukuna's part that makes reader deserves better. Besides, Sukuna doesn't hate anything and only cares for himself and things pertaining to him (JJK book). Hence, since reader is a part of Sukuna ever since he falls in love then it's just in his nature to protect reader not just physically but mentally and emotionally (not without struggle ofc). There's no "doomed" reference unlike my itafushi fic where it's fixed on Spencer Reid and Maeve Donovan trope dynamic which has an urgency and importance I wanted to show between the itafushi ship and spencer/maeve ship (parallelism, symbolism, dynamic, characterization) but also plot points. And despite the chaotic world, it's still realistic for law enforcements and anarchists to win against regime, corruption, and dictatorship. That's all I can give for now.
