The sycamore leaves of Southern University are covered with golden autumn leaves. Lin Xiran, a cute junior girl from the Department of Literature, reported that she was lost when she arrived. She accidentally broke into the orientation center of the Department of Computer Science and bumped into Lu Zeyan, who was surrounded by everyone. An error in obtaining the wrong information made Lu Zeyan, who was cold on the outside and hot on the inside, become her exclusive guardian: silently carrying her luggage, secretly leaving sweet and sour pork ribs, and leaning towards her with an umbrella on rainy nights. Lin Xiran also responded tenderly, writing poems to include in his professional book, and staying up late studying e-sports rules just to have a common topic with him.
From the ambiguous pull of two-way secret love, to the confession under the starlight on the rooftop, to the daily sugar-coating of campus lovers, the two work together to overcome academic pressure, competition challenges, and the test of graduation in a different place, and grow together while supporting each other. In the end, they returned to the sycamore tree where they first met, changed into school uniforms and wedding dresses, and stayed together for the rest of their lives. This is a campus sweet show without any abuse or scum, hiding all the beauty of youthful love.
