Otome Game no Mob desura naindaga

Issac, who has memories of his previous life in Japan, is an apprentice gardener of a duke’s family. The duke’s house was the house of a rival daughter of an otome game played by his younger sister! But I realized that I’m not a mob in the game. There is no possibility of being caught up with the rival and facing ruin. Does it make sense for me to have memories of my previous life? That’s why I aimed to become a gardener without worrying about being in the world of an otome game.
