In high school, Su Yinan and Shen Jiarui both liked each other but missed it because they were too timid to confess. Many years later, while working, Su Yinan was working overtime in the company one night and received a call from her mother, saying that she had found a box with a bear pattern. Su Yinan remembered that she secretly liked Shen Jiarui that year, and thought to herself that it would have been better if she had been braver at that time. But God gave her the opportunity to go back to her high school days, but what she didn't know was that Shen Jiarui had also returned to her high school days, so how would she feel when they met again.
Concept: It would be a pity if we missed someone we liked in high school because we were timid, so we should be brave if we meet someone we like very much.
