Despite being born into a privileged family, the protagonist had a strained relationship with his family. After being reborn in a magical world where the empire has conquered the entire continent, he becomes the emperor's eldest son, Asha. However, due to his lineage, he is not the heir. Deciding to leave the responsibilities to his younger brother, he aims to create a close-knit family, something he never had in his previous life. Living on the outskirts of the palace, he indulges in alchemy, a neglected field, and creates an intelligent entity named Sefira. While trying to enjoy his freedom, he faces the suspicions and provocations of the nobles. Pretending to be a child, he evades or retaliates, all while expanding the possibilities of alchemy in the forgotten corner of the palace. 'When will I get to meet my brother?' *Please note: - The protagonist remains in a weak position and does not aspire to become the emperor. - There is no revenge that results in deaths. - Every five chapters, a side story is inserted.
