The girl Han Shitong came to S city to study in the second year of high school for some reasons. She accidentally bumped into a boy at the airport and fell in love with him at first sight. Later she learned that he wanted to live under the same roof as Zhou Jinxun and was a classmate in school. Han Shitong started his own secret love journey. Later, during the college entrance examination, her mother suddenly fell ill. Han Shitong sent her to the hospital, but she missed the college entrance examination. Later, she learned that Zhou Jinxun went to Qihua University. In the second year, she took the college entrance examination again and was admitted to the same university group, but she learned that Zhou Jinxun was going to study abroad.
One day three years later, because Han Shitong's friend had a stomachache, she accompanied him, only to find that Zhou Jinxun was already a doctor.
Intention: a sudden whim.
