Tsuihousareta Koori no Seijo wa Bouen no Ouji ni Metorareru: Danna-sama ni Chouaisarete, Kondokoso Ibasho wo Mitsukemasu!

“Sorry, but I need you, so I’ll never let you go.” In the remote snowy land of Frezeris, Princess Sheila, the youngest of the royal family, possesses ice magic far too strong for her to control. Once praised as the “Saint of Ice,” she’s now scorned as a failure and treated as an embarrassment within the palace. One day, a sudden marriage proposal arrives from Prince Isaac of Abhajik, the desert kingdom known for its blazing heat. Feared across nations as the “Flame Demon,” Isaac’s reputation is as fiery as his magic. Cast out of her own country under the guise of this engagement, Sheila is sent off like a burden. However, it soon becomes clear that Isaac’s uncontrollable “infernal flames” can be calmed by one thing— Sheila’s kiss…?! A heart-melting newlywed love story between a scorned saint and the feared prince who can’t let her go!
