My Twins Are Actually Quadruplets Manga

Dorothy's own twin sister Stella drugged her and threw her into a one-night stand with Albert — leaving her pregnant with quadruplets. The instant she blacked out after delivering Oscar and Grace, Stella made off with the newborns and handed them to Albert, swearing she was the woman from that night. What Stella never counted on: Dorothy survived her scheme and secretly gave birth to two more — Connie and Luke. Seven years on, Dorothy comes home a formidable woman, her true identity buried, hunting for the children stolen from her. And then their paths collide. Connie and Luke are carried home by Albert… while Oscar and Grace land at Dorothy's door.
