Lin Nian has nothing: no job, no savings, no future. She's broke and struggling to get by, but then she picks up a canary, the kind that can turn into a human.
Canaries are delicate and hard to care for. They need time, money, and love.
Unfortunately, she has none of those. All she has is a cramped rental with no air conditioning, cheap combo meals, and empty promises.
But the canary really is beautiful and refined, a delight to have around, and an asset in every way.
She shamelessly tries to keep him, promising she'll definitely get him a big house one day.
Later, she gets a job at a convenience store. While at work, she gets a message on her phone. She opens it and sees that the lights at home have been replaced, and there's an air conditioner, a TV, a soft sofa, and everything else. There's even a table piled high with freshly cooked food.
Suddenly, life feels full of promise.
Lin Nian smiles with satisfaction. This canary is worth keeping!
After arguing with his family and running away from home, Gu Yu suddenly suffers from low blood sugar and faints. He can't stop himself from transforming into his true form, and when he opens his eyes again, he's in a home where even the air reeks of poverty.
He's the son of the richest man in Shuishi, a bona fide rich kid, and he's never lived anywhere this shabby!
Besides, who rescues someone and takes them home instead of to the hospital? Something fishy is going on!
Later, he grows curious about Lin Nian and agrees to her terms.
He wants to order takeout, but Lin Nian brings him a cheap combo meal worth just a few yuan. He tosses it aside in disgust.
In the middle of the night, he sweats from the heat and seems to see a ghost. He wants cold water but there's no fridge, and he wants to play games but there's no computer.
What makes him even more curious is Lin Nian's color vision disorder and her ability to see ghosts.
Then he demands, "What else does this house have? If you have no money, don't keep a canary!"
Lin Nian answers, "It has you!"
Curiosity is the beginning of love. He sells his watch and clothes to make life more comfortable and convenient, and even learns how to cook.
The two are drawn to each other and gradually grow closer. Gu Yu declares, "You can keep a canary even if you're broke. I'll pay for everything!"
