This Bat Cub Looks Weak

Dorothy spent ten years in this world before returning to her biological father, during which time she acquired a system of multiple identities. Knowing everyone's true identity, she pretended to be an innocent and naive girl, gaining everyone's approval. But what she truly is is a lazy bum, wondering whether she should plan something big or just relax and go to sleep. However, no one knows that Dorothy is also traveling the world in her other identities, having a wild and carefree time. Today is another day of her loving-hating struggle with herself. The female lead is a true powerhouse, but she just wants to be a lazy bum. The multiple identities are numerous and complex, and may contain personal opinions, so please don't be offended. The relationships with these identities are purely platonic and without romance (hugs, holding hands, flirting don't count!), and there will be no revelation of her true identity. There is basically no romantic pairing; if you want to see a romantic pairing, please leave a comment in the extra chapters. Theme: Growth.
