Xu Zhixia and Jiang Yichen are childhood sweethearts who grew up together.
Jiang Yichen and Shen Yubai are close brothers who have known each other since elementary school.
The three of them have known each other since childhood, but Xu Zhixia and Shen Yubai have always been just acquaintances.
Lin Wanzhi was Xu Zhixia's best friend only in junior high school. The four of them happened to be in the same class, but they had very few interactions. Even because of some trivial matters when he was young, Xu Zhixia directly regarded Shen Yubai as a mortal enemy that he hated.
It wasn't until they graduated from junior high school and got together because of games that the relationship eased slightly. But even though the situation has eased, it still can't stop them from fighting each other as soon as they meet and competing with each other as soon as they open their mouths.
No one knows that in those tit-for-tat daily routines, the seeds of heartbeat have already been quietly planted.
Concept: The heartbeat in youth is never a sudden coincidence, but the sincerity of slowly getting closer to each other amidst the noise.
