On his thirtieth birthday, Xing Duozhen received his PhD in physics. The moment he clicked the shutter button on his graduation photo, a woman in a white suit burst into the frame - it was his first undergraduate love, Shen Nian, who had disappeared for seven years.
Back then she said she would disappear after breaking up, but now she smiles and says "doctorate, happy graduation", as if those seven years were just a nap.
In the first cup of coffee after their reunion, she used a financial model to analyze his probability of being single, and he used Schrödinger's cat to test whether she still loved him. Underneath the dignity of adults, there is a question that neither of them dare to touch: What happened back then?
Until a crumpled train ticket, a deleted text message, and a lie that had been hidden for seven years were revealed. It turns out that they were all pushed to different life trajectories by the same person.
The misunderstanding was resolved, but the seven-year gap remained. He is about to go to a top overseas laboratory, and her workplace battlefield is at home. Can the promise we made back then - go to Qinghai Lake to watch the stars together - still come true?
This is a story about missing and waiting. A straight man with a Ph. D. In Physics × a sober heroine from an investment bank, reunited after breaking up, pushing and pulling to the extreme. This time, we're not talking about formulas, just love.
