When Jiang Wan opened her eyes, she became Su Wan, a vicious female supporting character in youth novels who would do anything to steal the male protagonist. She was also bound to a "survival system" - she must have a 100% favorability rating for Gu Chen, the hidden boss in the book, otherwise she would be wiped out.
Faced with Gu Chen, who was cold, distant and intimidating, Jiang Wan bit the bullet and launched a strategy: the wrong breakfast, deliberate encounters, sneak peeks in class... But they repeatedly ran into obstacles. The mess left by the original owner made her even more distressed: she was surrounded by the school idol Shen Yifeng's fan girl, forced into marriage by her family, and isolated by her classmates.
However, in repeated confrontations, she glimpsed Gu Chen's loneliness and tenacity under her cold shell; Gu Chen also saw her kindness and bravery after shedding the "evil" label. From being forced to get closer to sincere commitment, they work together to resist family pressure and academic challenges, and experience heartbeat and growth together in their youthful years.
When the mission becomes sincerity and prejudice turns into understanding, this unexpected time travel that begins with "life extension" finally becomes a perfect love that transcends obstacles and spans from campus to the rest of life.
