Ten-year-old Lin Beiyi (formerly known as Lin Qiao) fell in love for the first time in his life with Su Mo, an English teacher who came to his home to make up lessons. At that time, Su Mo was still a freshman in the School of Foreign Languages, but like a ray of light, she not only made Lin Beiyi fall in love with English, but also quietly changed her future direction.
In order to get closer to this beam of light, Lin Beiyi pursued all the way: he was admitted to Su Mo's alma mater and major at the age of 20, and because the threshold of the joint venture company where Su Mo was working was too high, he decided to study abroad to improve himself.
On the day he returned to apply for a job, Lin Beiyi met Su Mo again at the interviewer's table - now she is the revered President Su in the company. In ten years, Lin Beiyi grew his hair long and changed his name. Su Mo thought she looked familiar, but he did not recognize the little girl who once leaned at the desk and listened to his lectures.
After successfully joining the same department, his former "teacher" became his immediate boss, and Lin Beiyi finally stood closest to Su Mo. This one-way journey spanning thirteen years has turned into a long and determined journey of pursuing love in the office. When Su Mo finally cleared away the fog of memory and saw clearly her already throbbing heart, she chose to hold Lin Beiyi's hand tightly and let the pursuit of light eventually become a two-way chase.
