The carved window lattice of the ancient town in Jiangnan reflected the silhouettes of two children. He tied the bracelet he knitted by himself around her wrist and promised to see all the buildings in the world together in the future. Ten years later, she was a small-town girl who broke into the ivory tower with her father's last wish. She was at a loss in the architecture class and hid her confusion behind the drawing paper; he was a dual-study scientific god living in the family's expectations, arming himself with coldness and alienation, and locking deep love in his heart. After getting lost in a school opening ceremony, the faded bracelet reunited. He recognized her, but she had long lost her childhood memories. When Shen Xingyue, who has low self-esteem and cowardice, meets Lu Beichen, who is cold on the outside and hot on the inside, when Qin Yutian, the flower of the high mountain, meets Lin Yiming, who is cute and straight-ball, when Su Nian, who is sober and sharp-tongued, meets the gentle and forbearing Gu Yan, and the little sun Zhou Yan who always wears a smile, the youth of seven young people are intertwined. Pressured by family, pulled by secret love, and made to choose their dreams, they stumbled around the university campus, bidding farewell to their past selves while rushing towards a future that belonged to each other. It turns out that the waiting across mountains and seas, the wandering growth, are all just for a destined encounter. You and the stars in the sky are the answers I have been looking for all my life.
