The main characters in A Pair of Mandarin Ducks' Promise on Campus are Lin Xiaoman and Xiaoye.
Lin Xiaoman is absolutely stunning. Her smile is sweet and charming, and everyone turns to look when she walks across campus. Xiaoye seems a little cool, but the tenderness in his eyes is impossible to hide.
Their story begins by the school lake. One day, Xiaoman is staring dreamily at the mandarin ducks in the water when Xiaoye suddenly comes over. “Why don't we make a promise like they did?”
After that, it's one sweet moment after another: hiding on the sports field to watch the stars, sharing half a slice of cake on the way home, and Xiaoye highlighting the important points for Xiaoman before exams. What exactly is their promise? No spoilers! Let's just say their everyday life together is very sweet~
