On the first day of the third year of high school, Tan Mengmeng, a lively and cheerful transfer student, met Ye Yunchen, the indifferent and alienated class monitor, under the sycamore tree. From then on, the intertwined destinies of the two began. Ye Yunchen silently collected her lost hair rope, pasted her torn love letters, and wrote "My Sunshine" on the back of the photo, but never spoke. After graduation, they went their separate ways. In the past seven years, Tan Mengmeng has grown and transformed in the workplace, while Ye Yunchen wrote unsendable greeting cards on his birthday every year, holding on to his unspoken love.
Seven years later, they met again in the workplace. He was the superior president, and she was the hard-working project leader. Misunderstandings, rumors and family pressure run through it, but the emotions deep in my heart never fade. From fighting side by side in project crises to making firm choices in the face of business marriage rumors, Ye Yunchen used actions to fulfill his promise of "I will solve it". This is a story about time, waiting and courage. In the season when the sycamore leaves turn yellow again, all the unspoken love will eventually pass through the gaps of time and usher in the answer.
