Hi, I read a manhwa/manhua recently where: Protagonist is a regressor World-Setting is medieval He belonged to some tribe He regresses back to when he was adopted by the knight who killed is father (in a duel) The knight has other kids whom he adopted. The protagonist foils a plan where an enemy would have killed one of his step brothers I read this very recently. Couldn't find it again. Fairly certain it was new series, since there weren't a lot of chapters when I read it.
