So MC reincarnated into the story as a 2nd try for his former life. Mcs brother is hos sister from his first life and his love is his boyfriend from his first life (that's why he thought MC had a sister not a brother). Qnd the sister is freaking put bc her brother should die according to the story.
Meanwhile ML is being a dick to his sister/brother instead of talking it through when it should be so obvious they both know about the book bc he is affraid of more changes that could cost him his life, Affekt lil siblings life negatively and or prevent him from returning to his former life.
This will be a happy ending once they're all able to put their three braincells together
