[Two male leads + bottom lead + university campus + mutual healing + sweet romance + both are each other's first and only]
Chen Zhiyan falls “in love at first sight” with Duan Lin, the freshman representative giving a speech beneath the national flag. Unexpected encounters and unforeseen happiness can come at any time. A young man's heart flutters, vivid and fervent, and Chen Zhiyan takes it in stride. But was it really “at first sight”?
After waking from a car accident, Chen Zhiyan has lost every memory of Duan Lin. He forgets their promise to get into the same university. He forgets that they promised to be the first to wish each other a happy New Year every year.
Surrounded by his family's love and his classmates' concern, Chen Zhiyan remembers everyone and everything except him. Duan Lin listens from outside the hospital room as Chen Zhiyan talks about having forgotten him. He hides the wall covered in their photos and puts away the diary documenting every flutter of their young hearts.
When we meet again, my heartbeat recognizes you before I do. The moment our eyes meet, my brain is still calculating the distance, but my heart gets there first, shattering every pretense of composure and falling into the summer we left unfinished. From a boastful teenage vow to become the city's top student, followed by a game used as an excuse to confess, to getting swept up in a play at the campus arts festival without even realizing it; from concealing each other's inner wounds to stripping away every disguise, they finally understand that even two broken moons can come together to form a whole galaxy.
