The Hidden Beauty

【Pseudosiblings, Forced Possession, Long-plotted Scheme】 After her true identity is revealed, Shu Yun remains in the Marquis household but faces constant bullying from the real heiress. When forced into a rural marriage, she turns to her former elder brother for help. He gently comforts her and takes charge of canceling the engagement.

The entire household treats her coldly except her brother, who allows her to keep calling him "Brother." Shu Yun realizes he is her only refuge and begins carefully pleasing him. One day, under the influence of a love potion, they share an intimate night. He promises to keep it secret and find her a good match afterward.

However, every ten days, she awakens in his bed. When the Marquis' daughter is about to marry, the bride disappears. In a dark private residence, Shu Yun’s wedding dress is torn away as her brother imprisons her. She finally understands his meticulous trap.

Xiao Ye always knew what he wanted—the girl who was never his sister but destined to be his wife. He schemes relentlessly, refusing to let anyone else touch his beloved. After Shu Yun escapes, he searches frantically until discovering her in Nanzhou, about to marry his sworn brother.

Note: The story avoids宅鬥 (internal family strife), begins after their pseudosibling relationship ends, and features a slow-burn plot with the male lead's schemes intensifying from Chapter 14.
