There is no male protagonist, no official match, and she may have a few boyfriends, but the man will not affect the speed of her drawing the sword, and is more likely to become the sword in her hand. The heroine will be miserable in the first half, probably asking for help from a non-standard "boyfriend" to learn how to accumulate strength, and may give birth to a daughter. In the second half, she will gradually grow up, change her name more than once, and eventually become emperor and have a harem. Savage growth, no taboos.
Intention: Growth and Counterattack
