Demon Slayer: I'm Xiaoli, and I Want to Stick with the Crowd

To catch her younger brother Kong Lan, who was causing trouble everywhere, Xiao Li set out to confront him in a fierce battle. Kong Lan demanded to know why, as a monster, she was always so different from the others. Other monsters either ate people or harmed them. Why did she always insist on doing the opposite? Unfazed by his challenge, Xiao Li calmly replied as though everything she did were perfectly ordinary: “You eat people, so I choose to befriend humans.” While the other monsters planned to team up with ghosts and build a huge granary, Xiao Li said, “I'll help the humans get rid of you instead. I refuse to be an evil monster with blood on my hands.” Perhaps a monster's life could have a different meaning if she tried to live peacefully with humans. And she could also fall in love with a handsome guy named Kyojuro Rengoku. Don't ask why. He's just that charming.

[Top-tier female lead × sunny boy] Come see what kind of sparks fly between a goddess-level heroine and the eldest brother. Sweet moments and angst will both come along, in whatever measure the story calls for. The ending is guaranteed to be happy.

I'm a pretty bad writer, so please point out anything that needs improvement.
