Seraphina, the 120‑year‑old White Dragon matriarch, suffers her fateful hundred‑year heat cycle. On a cruise she marks Eli Hart, sharp‑witted human CEO, binding him as her blood contractor. Haunted by century‑old secrets, they uncover Eli’s ancestor was the gardener’s boy Seraphina once loved, whose memories were sealed long ago. The twisted exiled Blue Dragon elder Samuel schemes to seize dragon power by using Eli as a blood‑resonating vessel. Trapped between dragon‑clan intrigues, old curses and blooming true love, the pair fight against Samuel’s dark ritual, rewrite the cruel ancient vessel rules, defeat evil forces. They break the master‑contractor barrier, welcome their dragon‑blood children, and build an equal, loving family combining dragon heritage and human life.
