My Youthful Romance Really Does Have Something Seriously Wrong with It

As an ultimate menace who combines a self-admiring good looks, a human meme machine, and a destroyer of romantic moods, Zhou Che has a flexible code of conduct:

He's politely distant and perfectly civil with strangers, shamelessly obnoxious with people he knows, and has a vast store of useless thoughts in his head. He's good at delivering lewd remarks with a straight face and blaming others before they can blame him.

He thought college life would be all about admiring his childhood friend's long legs, grabbing juicy grilled sausage from a street vendor, and directing teammates from the fountain in the Valley.

But his tsundere childhood friend next door, Su Qingyu, is always spoiling for a fight, making it her daily mission to twist his head off and kick it around like a ball.

Then his parents go traveling and suddenly move a distant cousin, Jiang Wanning, into his place. According to them, she's had a hard life and can't even look after herself.

Looking at this maturely curvy woman who sets the kitchen on fire every time she cooks,

this soft-spoken older girl who looks pitiful and teary-eyed in public, but enjoys teasing an innocent college guy whenever no one is around...

Zhou Che clutched his faintly aching conscience and fell into deep thought:

"What a disaster... Mother, you call her a helpless orphan? This is clearly a reincarnated Daji sent to the countryside to provide targeted relief!"
