คืนคําสาบานผูกพันธะคู่แท้

Elara, the Thorne family's adopted daughter, grows up with the three Thorne brothers, who vow to protect her and agree one will marry her. Seraphina, the elder's daughter, frames Elara by faking evidence that Elara harmed her. Deceived, the brothers turn on Elara and assault her; Fenrir, the eldest, personally casts her into a bottomless abyss. As she plummets to certain death, Kaelen—the Hellfire Wolf King and Alpha King—rescues her. Between life and death, they forge a mate bond.
