The Archmage She Betrayed

Prince Charles seals the dragon alone, becoming Rose Kingdom's patron saint. His fiancee Lena deems him useless, cheats with Regus, and exiles him. Unknowingly, Charles has regained peak power, reclaims his divine weapons, and tears space away. Seals collapse; demon Klaps slaughters the city. Lena falls, and she pays for her betrayal with her life.
