During the chirping of cicadas in the summer of childhood, Tang Yue and Zhang Hui were inseparable playmates. They shared the same piece of watermelon and whispered under the old locust tree. Zhang Hui was the brightest light in Tang Yue's youth. But a sudden change forced Tang Yue to leave in a hurry, without even being able to say goodbye. This immature friendship was swept away by the years.
Many years later, at the door of the university dormitory, Tang Yue was stopped by a shout. It was the person she had always cared about in her heart. Her heart suddenly tightened - those familiar eyebrows had long since lost their childishness, and they had grown into a cool and dazzling academic master. The excitement and guilt of the reunion made Tang Yue both happy and timid. She quietly approached and re-entered Zhang Hui's life as a roommate.
They went to the library together to overcome problems, and fought side by side on the competition field. Their tacit understanding was just like before. It's just that Tang Yue has always hidden two secrets: the reason why he left without saying goodbye when he was young, and the secret love that has never stopped and become increasingly fierce over the years. She guarded this concern and looked forward to the day when she could muster the courage to confess everything to Zhang Hui.
