Rubina, the eldest daughter of a baron's family, had her engagement broken off shortly after her father died of illness. The man in question seems to have decided to marry Rubina's younger sister, who is an incredibly beautiful girl. Just as the two were about to kick her out of the house, a knight named Cress appeared before Rubina in a magnificent carriage. Cress was the knight Rubina had previously rescued when he was injured and collapsed. Having nowhere else to go, Rubina was given a job as a servant at Cress's mansion. But this knight, despite his wild and strong appearance, sometimes shows expressions and gestures that are somehow adorable, like a big dog... A sweet and bittersweet romantic comedy featuring the adorable knight Cress, whose tail-wagging antics create a charming contrast, and the spirited and reliable Rubina! ___ [Original Web Novel](https://ncode.syosetu.com/n9726hd/)
