Tenseisha no Watashi ni Idondekuru Mubou de Yuubou na Shoujo no Hanashi

I'm glad i found this novel again after few years has passed, i just read the story before without knowing Kazuharu Kina is the illustrator. The rivality story beetween the MC and heroine kinda heartwarming and have strange nostalgic feeling. Seems like the dreams that you have when child being adapted to a novel. You rebirth with all the knowledge you already had from previous life, and seeing as super clever person from the others clever person side. The story has a related fantasy as well, is like someone reincarnated write itself This have well executioned ending, and i recommended it.
