On the first day that Su Miaomiao transferred to Jiangcheng No. 2 Middle School, she blew up the campus forum with a "public challenge" - facing Shen Yi, who was recognized by the whole school as the perfect school boy, she not only bluntly refuted the opponent's debate views, but also publicly "complained" about the lack of warmth in his speech. This head-to-head confrontation made everyone expect to see the freshman being "cold-treated" by the school boss, but the result was surprising: Shen Yi, who has severe mysophobia and never borrows personal belongings from others, turned around and handed Su Miaomiao his custom-made water cup; he was a man of words and could not even answer questions in more than five words, but he chased after Su Miaomiao every day and "naggled": "Have you had breakfast?" "Let me check your notes" and "Let's go together after school." As Shen Yi's abnormal operations increased, speculation about the relationship between the two became more intense. It wasn't until a yellowed old photo leaked out - in the photo, five-year-old Shen Yi was holding a lollipop and shouting "daughter-in-law" to Su Miaomiao with braids in a baby voice, that everyone finally realized. A year later, the childhood sweethearts entered Beijing University together and continued to spread love on the wider campus. The sweet daily life of the "Miaoyi" group has become recognized as the best example of youth.
