Relife Player 

After 30% of Korea's population was massacred by monsters, Players were the people's last hope. In a battle against those monsters, a Player named Noh Eunha was on the verge of death, but he was miraculously sent back to when he was a baby! Now that he knows what's to come, he's building up the mana he lacked in his past life while trying to convince his parents not to make the same choices that led to their deaths. But how can a 6-year-old Eunha convince his parents that he knows best? (Source: Tapas)
