From school uniforms to adulthood, Chu tide and Lu Zhili have been best friends for seven years in the eyes of others, but no one knows that behind this tacit understanding lies Chu tide's secret love that he has not revealed for seven years.
Her love was never a vigorous obsession, but integrated into the details of daily life: quietly exploring his daily habits and remembering them in her heart, the tenderness in her eyes when she looked at him, and the disguise of saying "we are best friends" with a smile every time she wanted to say something but stopped. A confession in student days was blocked by his understatement of "just be friends". The two spent a long period of alienation and finally returned to each other, but no one dared to touch that layer of window paper.
Over the years, he has always been single and never had a fixed person by his side. He has always been gentle and considerate to her like no one else: silently accompanying her when she hit the bottom, accompanying her to every distant place she wanted to go, and seeing all the prosperity in the world that she longed for. And she also kept this secret, her heart and eyes were full of him. She did countless stupid things like secretly falling in love, but she always regarded herself as a friend. She was afraid that if she crossed the line, she would lose her qualifications to stay with him. Seven years of companionship, countless tacit understandings and coincidences, half-truths and half-false jokes from parents, are they habits, dependence, or unnoticed love hidden in the bottom of my heart? When the details of the secret love accumulate, and when the identity of best friends becomes a shackles to each other, this emotional pull that spans many years will finally have an answer.
