Seven years ago, Duke Kyle of the Blazing Phoenix clan, under the influence of a love potion in the forbidden forest, crossed paths with Elly, a runaway bride from the Ice Cliff tribe. Their ice and fire magic intertwined, leading to a night of passion. Both fell unconscious afterward — Elly lost her memory and all her ice powers.
Seven years later, Elly struggles to make a living as a herbalist with her son Leo. When Ice Cliff tribesmen force her to return, Kyle rescues her. To evade an arranged marriage, Kyle invites Elly and Leo to pose as his wife and son at the Blazing Phoenix mansion.
Leo's striking emerald eyes — identical to Kyle's — and his rare dual ice-fire血脉, along with the awakening of the Phoenix totem, confirm to Kyle that Elly is the woman from seven years ago. The noblewoman Luna, jealous and scheming, conspires with Ice Cliff lord Sarlin to kidnap Elly. After obtaining the Ice Crystal Scepter, Elly uncovers the truth of her heritage, regains her ice magic, and vows revenge for her mother. Luna forges evidence to sow discord between the lovers, pushing them into a crisis of trust as the thousand-year feud between the two clans erupts.
