I’ll Live A Long Life to Adore My Absolute Fave—Currently My Stepbrother!

My absolute favourite character from my previous life became my stepbrother from my mother’s remarriage. This world is that of a nurturing simulation otome game. My stepbrother was a capture target in that game. And I became the younger brother from his memories, the one who only appeared in his personal story and was supposed to die soon! ‘Honestly, I don’t care if the younger brother of my absolute fave dies! But no, I can’t die until I see my absolute fave grow up! I’ll live! I’m going to smash the death flags and adore my absolute fave today as well!’ This is the story of a reincarnated younger brother in an otome game and his struggles with all of his death flags.
