Jun Ping (played by Wang Chenhao), an ordinary junior, dreams of becoming a director. One day, he met a girl wearing strawberry pattern underwear on the rooftop, and fell in love with her figure in the sunset at first sight, but he didn't know the girl's true face and identity. Under the inference of his friends, Jun Ping thought that the owner of the strawberry pattern underwear should be the school's celebrity Xi Ye (played by Dun Jingyi). In this process, Jun Ping met Dong Ling (played by Ren Zhiyan), Bei Yue (played by Guo Xuemeng) and Nan Gong (played by Zang Yusi) with different personalities. And who is the owner of the strawberry underwear makes Jun Ping more and more confused. Dong Ling, who loves reading, wrote a novel called "Hormones", and Jun Ping decided to record it with a DV in his last summer vacation in college. In this summer, Jun Ping spent the most gentle, lingering and entangled summer with these four girls. In the end, can Jun Ping realize his dream? And the four girls in the four directions of southeast, northwest, and northeast, which path did Jun Ping choose? This film is adapted from the manga of the same name "Strawberry 100%" created by Mizuki Kawashima. It is the second work of young director Zhang Neixian after "Unemployed Youth".
