help!!

so this isn't manga related but I've been looking for this novel for almost 2 years now.

it's a chinese novel that I think is connected around reincarnation or time change . the fl enters the entertainment circle as a manager for a company and dresses as a boy because of all the misogyny in the industry (also partly because the ml was jealous thinking that others would flirt with fl). the fl is looked down upon in the company and doesn't even get an idol/actor in the beginning. She then meets 2nd male lead there when she finds out that his original manager was blackmailing him to sleep with him in order to get roles in movies and stuff. the fl offers to the 2nd ml to accept her as his manager to escape from his og manager and 2nd ml agrees. the fl then works hard to make him popular and begins to succeed. (2nd ml is quiet, calm type btw). one night when fl is in her female form, she goes into a cafe and orders her fav dessert (?). she gets the last one and ta-da the guy behind her who just so happens to be the 3rd ml wanted the same thing. fl notices his disappoinment over not getting the dessert so she gives hers to him and the 3rd ml falls for her there and then (our fl is quite the beauty mind you). when the fl (in her male form) goes to a audition for a role with 2nd ml, she meets the 3rd ml there and he doesn't recognize her because of her not being in her female form. the 3rd ml is a popular actor of that company (bc rich and handsome) and he was also auditioning for the same role so he began to bully fl and 2nd male lead (our 3rd ml is quite the mischievous type ). the fl gets pissed and tries to think of a solution after the auditions (the 3rd ml was basically blackmailing the director of the movie they were auditioning for). fl soon finds out that 3rd ml has been looking for her ever since that night (dessert and whatnot) and decides to use it to get advantage. she calls 3rd ml over and tells him that she (fl in male form) is actually the brother of that girl (fl in female form). fl blackmaiils him by saying that he (3rd ml) can only meet the girl (fl in female form) if 3rd ml takes fl (in male form) as his manager. the 3rd ml totally head over heels for fl in female form agrees. over time, both 2nd and 3rd ml fall for our fl but she unfortunately or fortunately already has 1st ml, the typical possessive rich ceo. the mc does eventually reveal that she's a female though.

please, please help me find this novel!! it doesn't matter if the book you're thinking of isn't exactly like my description, you can recommend as long as you find them even a bit similar. i absolutely adored it and cant find it ever since my old phone broke. idk if this will help but I originally found the novel on kongfu books.
