Xu Yan
The noisiest one in the world is Xia Chan, and the silent one is also
Xu Yan was the mute cicada, hiding all his love in his chest, flapping his wings deafeningly where Shen Tingxia couldn't hear him.
Xu Yan had a childhood sweetheart named Shen Zhixia
The whole community knows that their two families are good friends. They grew up together. Xu Yan remembers what Shen Zhixia said casually, remembers the taboos, and remembers her menstrual period.
Xu Yan has a calendar. Starting from junior high school, there are always red circles on the calendar for a few days of each month, and the time is not fixed. He does not write the reason, but only draws a small red circle.
Once someone else looked at it and asked him what it was, but he didn't answer. Only he knew in his heart that it was the day when Shen Zhixia was menstruating.
Shen Zhixia sometimes teases him about whether he likes her, but every time he says coldly that he thinks too much, no. Shen Zhixia didn't notice that his ears had quietly turned red.
Shen Zhixia said it so many times that she believed that he didn't like her.
Until Xu Yan accidentally discovered a calendar when he was making brown sugar glutinous rice balls for her, Xu Yanzang's mind was broken.
Concept: I have a calendar about you
