All Unsent Information Is Published to the Whole School

On the eve of graduation, a system failure suddenly occurred in Haicheng University's "Time Mailbox" - letters written by everyone but never sent may be seen by the people mentioned in the letters. When Zhou Yan received the notice, he found that the letter he wrote four years ago had been read by Lin Qiao. In Lin Qiao's mailbox, there were six letters related to him. For the first time, they knew that they had not been in love with each other all those years, and for the first time they saw all the unspoken waiting, temptation and disappointment of each other. But can emotions that are not sent out really be considered expressions? Is it still too late to say those words that are four years late, dare not say, and have been waiting for?
