New chance in different world
Lila wasn't happy with her life after making some wrong decisions. Introverted and shy to the point it hindered her from engaging in basic interactions, she felt lonely due to her inability to talk with women, the only gender she's interested in.
Lila desired to better herself, but she couldn’t do so without assistance after all this time. This changed when she got into an accident that brought an end to the life she despised.
Someone calling himself an 'overseer of worlds' decided to save her from certain death. He offered her a second chance in a different world where even magic exists. He also 'blessed' her with many so-called boosts to make her life easier. Lila seized this opportunity and asked to become more outgoing, confident, and the like.
The overseer didn’t stop there, though. He enhanced every emotion and personality trait, whether positive or negative. Her physical stats were no exception, either. To complicate matters further, these boosts weren't always reliable. They occasionally overcompensated or even failed.
Lila worked hard to navigate her new and complicated situation while doing her best in the new world. She explored places, learned magic, finally found friends, and possibly more, all while enjoying a slow and easygoing life overflowing with fluff.
Unfortunately, she learned magic from a highly overpowered, easygoing, and somewhat unreliable teacher who became her first friend. This not only shattered the last bit of her common sense, but Lila's application of magic became rather sloppy, causing one bizarre incident after another.
She met many new friends and had an easygoing life filled with fluff 96% of the time. Still, her vast powers and the lack of common sense, combined with her being beyond carefree while rarely considering the consequences of her actions, made her life anything but slow.
