My Best Friend Stole My Fiancé, but I'm the One Having a Blast With a Troubled Handsome Knight

https://www.cmoa.jp/title/343563 Elena’s so-called friend stole her fiancé and, claiming to be pregnant, pressured her into breaking off the engagement. In a burst of anger, Elena hurled a teacup at her ex-fiancé, sparking rumors that she was a “dangerous young lady” who nearly killed her lover over infidelity. Wanting to escape the gossip, she left the capital for her late grandmother’s mansion in the northern borderlands. But upon arrival, she discovered Norbert, a knight in service to the border count, already living there, the mansion had been given to him. Norbert welcomed her without complaint and offered to move her into the servants’ annex, which she refused, and he insisted she shouldn’t have to stay there as the granddaughter of his benefactor. Since Elena loved cooking, she began preparing meals for the two of them. Norbert admired her red hair, often mocked by others as “the color of warm blessings," and genuinely enjoyed her cooking, unlike her ex-fiancé. His sincerity warmed her heart. Their life “under two roofs” began peacefully until her ex-fiancé and his mistress, supposedly still in the imperial capital, suddenly showed up, marking the start of Elena’s journey to finding happiness on her own terms.
