Tao Ning and Wen Yu are childhood sweethearts who live in the same old family home. They are in the top two of their grade at the same school and are recognized by others as double academic leaders. Tao Ning grew up under the protection of all the seniors in the dean, and they doted on the little sunshine. Wen Yu always stayed by her side, helping her to avoid troubles, accompanying her to make up for her weak subjects, using his unique preference to cure her occasional little anxieties, and turning her daily life on campus into exclusive memories full of sweetness.
