In the summer of Class 3, Grade 2, the wind blew through the sycamore leaves and the unspoken heartbeats of Su Yang and Song Zhixu. She has meticulous thinking when solving math problems, and he is clear and organized when doing physics papers. He is a "well-matched" existence in the eyes of the teacher.
But only Su Yang knew that every time he looked up at Song Zhixu's back, his heartbeat would skip a beat; only Song Zhixu knew that when he looked at Su Yang, his fingertips would quietly clenched. Just like the summer night wind, which looks warm but contains a coolness that only they understand. This two-way secret love is quiet and firm. No one says it, but everyone knows it.
Concept: The sober, restrained and two-way secret love between boys and girls.
