It's So Hard Being a Slacker in a Boy Band

I'm new to writing, so please be kind and offer your guidance. Thank you!

After countless hardships, Gu Chengcheng finally completed every mission in the quick transmigration world. She should have been able to relax and enjoy the fruits of her labor. But then something went wrong with the System, and before she knew it, she had been sent into the world of a TNT novel. Faced with this sudden turn of events, Gu Chengcheng thought, "If I can't change it, I'll just settle down and be a carefree slacker!" But reality loves playing tricks. Not only did she fail to get any free time, she was constantly chased by work. Her life grew busier and busier, as if she'd fallen into a whirlpool of endless activity.
