There is a bitter past buried deep in Lin Xuecheng's heart. That memory is locked in the depths of his memory and forced to be forgotten. It was an unrequited love in high school, and the embarrassing past of running away after confessing impulsively. Not only was this memory not sweet, it actually made his stomach ache every time he thought about it. Eight years after graduation, this incident has become a distant past.
One day, the branch company where he worked was about to be merged and relocated. Qianpeng Lin Xuecheng decided to cheer up and work harder in the new environment. However, when meeting his new colleagues, he saw a familiar face - his high school crush Su Jingchen, standing in front of him.
His classmates became colleagues. Lin Xuecheng tried his best to pretend to be calm, but what kept popping up in his mind was the embarrassing memory of unrequited love. She wasn't sure whether she was paying attention to Su Jingchen again because of nostalgia, or whether she was falling in love again, so she fell into a day of entanglement and thinking.
