Can you recommend some novels with black-bellied female protagonists and ever-changing personalities?

Must meet all of the following requirements (there is a deviation above the average (deviation) is meaningless (small is very normal), this side read very few novels (love is not big), so only read absolutely love) Female protagonist requirements 1. Black belly 2. Queen (dispensable)3. Character change (enthusiasm, indifference, etc. all depends on the mood of the female protagonist) 4. Feel like you know everything, will not be played in the palm of the hand (except for the male protagonist), or feel like you are a few hundred years old. If you are unhappy, you can throw it all over the world. 5. Your own ability is strong. 6. You have the intention of dressing up as a man to flirt with cute women. Absolutely do not want attributes:1. It is easy to get emotional.(It's best if no one can make her fall in love with (except the male protagonist). 2. Don't be embarrassed by the male protagonist's teasing. 3. Don't mix with men's clothing as the main attribute (can only be used as entertainment). Note:1. Perfect ending. 2. Love is complicated. The female protagonist falls in love with two men, but it is very annoying to choose an official partner. Absolutely not. 3. Please attach the plot introduction.(Personal opinion counts, not necessarily official)4. No restrictions on the type (time travel, now, online games, mythology, etc.`` as long as the attributes are right `any type is fine); all of the above must be included (except for the special indication in the parenthesis) Not counting, even if there is only one answer that matches, it is better than the answer of N parts with wrong attributes.
