Covert security company Vanguard is the last hope of survival for an accountant after he is targeted by the world's deadliest mercenary organization.

Zhou Can moved to school in a small town from a big city, a place he didn't like, and kept thinking about going back to where he had lived. His grades are very excellent, so he doesn't have to worry about study in the new school. In terms of personality, he is always quiet, doesn't like to communicate with people, and his ability to make friends is lacking. Yu Jiao Yang is a wild and cheerful girl who has very poor grades in this small town. They are two people who are very different in every way but as the two meet and form a very close friendship, they stay together through every obstacle they go through.

Going to the end with you is my greatest wish. The carefree late summer (played by Xu Ruohan) and the gentle and restrained early autumn (played by Zhang Kaitai) have witnessed each other's beautiful green years and spent many unforgettable moments with each other. They have the tacit understanding of childhood sweethearts and the courage to resist reality. His love is vigorous, and her love is unwavering. Perhaps the road to true love is not smooth. Misunderstandings and misses once brought two lovers to the edge of separation. But how can the right person get separated?
