"Cousin, your tricks might deceive others, but they can't deceive me; I used to play this game of feigned indifference myself, and though I had a hundred percent success rate, Qiao Ran is not like those targets of mine who could be easily fooled with little tricks.
Qiao Ran is neither like those naive girls who don't understand love, who are so simple that solving a math problem for them earns their adoration and love, nor is she like those gold-diggers who chase wealth to improve their quality of life, and can be won over with enough money and jewels.
She is equal to you in strength, which is why you deigned to become sworn siblings with her in order to avoid the fate of the Wen Family being targeted.
Given the situation, why don't you win her back and make her your wife? United, you would be a stronger force than as siblings, and that union could better secure the stability of the Wen Group?
