The Capital's Power Broker, My Official Brother-in-Law, My One True Love

[Capital power player × innocent substitute] [Angsty romance + groveling pursuit + political intrigue + white moonlight]

Gu Huaian, one of the capital’s most powerful men, is a ruthless king of the underworld who can turn the tides with a flick of his hand. He is also a well-known romantic. After his beloved wife, Su Wanqing, died of illness, his heart died with her, leaving behind only a cold shell that wielded power and schemed.

The only soft spot he has is his late wife’s younger sister, Su Xiaochen, a country girl he supports. He protects her like a child, lets her into his world, and finds comfort for his heartache in her face, which bears a faint resemblance to his beloved wife’s.

Su Xiaochen has been grateful to her brother-in-law since childhood, but as they grow closer, she falls for this unreachable man like a moth to a flame. She is willing to be her sister’s shadow, awkwardly imitating her, just to bring him a moment of warmth.

Until that day

What to expect: devastating romance, substitute trope, groveling pursuit, two leads with no prior romantic relationships, capital power struggles, powerful male lead, a college student’s rise, and the white moonlight versus the cinnabar mole.
