Help! The Crazy Young Master Insists on Calling Me Big Sis

[Resilient, Aloof Heroine VS Mad, Obsessive Young Master] Cheng Jiu transmigrated into the body of a woman named Cheng Zhenzhu. The woman was obviously a doomed extra. She'd actually dared to drug and scheme against her cousin, who was also the domineering CEO's girlfriend. If she wasn't doomed, who was? Fortunately, Cheng Jiu had transmigrated before the drugging. Unfortunately, even though she wanted to back out, the deed was done. Fortunately, she escaped trouble with the help of a certain young master. But even more unfortunately, that young master was a lunatic. Because of what happened, he set his sights on her, calling her “Sister Zhenzhu” at every turn until Cheng Jiu was spooked. No matter how fiercely she resisted or how hard she tried to get away, her entanglement with the lunatic young master only grew deeper, until she had nowhere left to run, as if it were fate. Excerpt: Cheng Zhenzhu didn't want to keep talking, so she awkwardly brought the conversation back around. “Young Master Chu, what do you want with me so late at night?” Chu Yan clicked his tongue and said aggrievedly, “Sister Zhenzhu, do you really hate me that much?” There was no way to keep this conversation going. Cheng Zhenzhu said to herself, “If that's all, I'll hang up...” Before she could finish the last word, she was interrupted again, just like last time. “I have something to say.” Cheng Zhenzhu: “...What is it?” “I'd like to ask you to keep me company tonight, Sister Zhenzhu.” Chu Yan's tone was frivolous. “The night is long, and it's hard to bear.” Cheng Zhenzhu didn't feel offended. She only asked calmly, “Does this count as the fourth request?” Chu Yan smiled. “That depends on how you behave tonight.” He licked the corner of his lips and asked wickedly, “Well, Sister Zhenzhu, will you agree?” Would you dare?
