I'm Not Human

While Yan Xiao was blowing bubbles in the river, a human picked him up and took him home. From then on, he had one lofty goal: to become human!

In elementary school, his classmate Xiao Ming said, "Yan Xiao, want to hang out after school?"

Yan Xiao replied, "No, I have to go home and do my homework. Thanks for inviting me."

"..."

In middle school, a passerby said, "Yan Xiao, your classmate Xiao Hong asked me to give you this. Make sure you read it."

Yan Xiao looked at the heart-shaped letter pressed into his hand. After opening it and taking a glance, he quickly found the classmate who had delivered it. "There are six misspelled characters in this essay. I've marked them. Please tell Xiao Hong to study hard and keep improving!"

"What the hell..."

In college...

"Look! That's the legendary handsome idiot Yan Xiao!!"

Later, at a training session titled How to Become a Qualified Human in a One-on-One Relationship:

An Tang said, "Yan Xiao, as your teacher, I have to tell you that humans are the most desire-driven species in the world. If you want to become a qualified human, you have to learn to have desires first."

Good boy Yan Xiao nodded. "Teacher An, how do I get one?"

An Tang said, "Come here, give me a kiss, and I'll tell you."

A powerful, strange species who only wants to be an ordinary good person, but doesn't need to eat or sleep and can't die, as the bottom;

A super-species who was supposedly an ordinary human long ago, but for unknown reasons never ages or dies, now lives deep in the mountains and helps humans kill other species, as the top.
