Yari Konda Otome Game no Akuyaku Mob desu ga, Danzai wa Iya nanode Mattou ni Ikimasu @COMIC

Kanda Hajime, a game-loving office worker, collapses from repeated overwork and wakes up as Rid, the villain of the otome game "Tokirera!". Awaiting him in the game is a bad ending of condemnation. In order to avoid condemnation, he uses his natural intelligence and the knowledge of games he has acquired before his reincarnation to first fix the discord in his family. A cold-hearted father, a lonely sister, and a sick mother. The measures Rid takes to save them go beyond the game's scenario and become a huge wave that engulfs the entire continent!
