Transformed, Then Imprisoned by My Brother

(Gender transformation: The male lead has a normal crush at first, then turns to captivity play later. The heroine falls for him before becoming a woman.)

Lin Qiufan and his friend Qin Yanzhou spent five years building a business together. Over those five years, their company grew bigger and stronger. One night, after getting drunk, Lin Qiufan accidentally became a woman because of a System.

What he didn’t know was that his friend had been secretly in love with him from the very beginning, including throughout those five years of building the business. The System made her live as a woman disguised as a man for a full year and a half. Hoping to turn back into a man, she had no choice but to keep pretending to be one. But she never noticed that the secret affection in her friend’s eyes was turning into possessiveness… She only realized their friendship had long since changed into something else when her friend kidnapped and imprisoned her.

(Anyway, it’s all in there, hahaha.)
