Both dramas involve the ML being asked to pose as his twin brother. In Fervent Kiss, its by his uncle, and the FL takes time to figure it out, whereas in Be Your Knight, the FL drags the ML into the story and the rest of their family, mainly their aunt, figures it out over time.
The rest of the dramas have different vibes, one in modern setting, the other in a more dangerous republican era setting.

Both are Republican Era mini dramas by the same director. Both involve one of the leads marrying/being engaged to the other's sibling who later dies; both relationships were not for love. They then cross paths with the other lead and the two team up for a united goal against their enemies, falling in love along the way. Both dramas have secondary couples, one half of which is the ML's sibling.
