What Bad Intentions Could a Little Jellyfish Have?

Jing Xi is a jellyfish with a big head and beautiful tentacles. He's as poisonous as he is adorable, and he was perfectly happy living in the sea.

Then one day, he turned into a fragile human. Clutching his jellyfish body, he stared in horror. Why couldn't he turn back?

The System looked at the poor little jellyfish. "...Sorry, I picked up the wrong person..."

To return to his original body and the sea, Jing Xi has to complete this world's mission: save the protagonist, Xiao Yunzhuo, before he turns evil.

Apparently, the protagonist is currently a miserable little guy who has been through a lot. The little jellyfish is full of determination. Don't worry, I'll protect him!

So Jing Xi diligently starts following and spying on him... no, observing and protecting Xiao Yunzhuo.

But things don't seem to go very smoothly. For example:

Xiao Yunzhuo is surrounded by several bullies, and it looks like he's about to get beaten up!

Jing Xi immediately rushes over to save the handsome guy, but he's so nervous that he crashes into Xiao Yunzhuo's arms. The poison he'd been carefully saving ends up in the boy's arm.

The boy slowly collapses. "Are you one of them too?"

Jing Xi: "!!!"

And then there's this:

Knowing Xiao Yunzhuo can't sleep at night, Jing Xi carefully brews him a "potion" to help him fall asleep quickly.

The next day, Xiao Yunzhuo lies pale in a hospital bed and looks at him. "Do you hate me so much you'd poison me?"

Jing Xi: "!!!!"

Later, it seems Xiao Yunzhuo discovers that Jing Xi's original body is a jellyfish.

Xiao Yunzhuo: "You're really not that poisonous jellyfish?"

Jing Xi panics. "I, I'm not... I'm not poisonous!"

Xiao Yunzhuo grips his chin and presses a finger to his lips. "Really? Then let me test that poison."
