The "38th parallel" in the middle of the desk is the main battlefield for Lin Wanxing and Jiang Yubai. They fight for erasers, scratch paper, and criticize each other's wrong test papers. They keep arguing every day. But no one knew that she would secretly stuff painkillers into his stomach when he was injured while playing basketball; that when he was called on by the teacher, she would secretly write the answers on the scratch paper and hand them over. The bickering is daily, the hidden heartbeat. It turns out that the secret love is, even the seventeen-year-old Feng knows it, but you don't know.
Concept: Those tit-for-tat daily encounters are all filled with unspeakable concerns. It turns out that secret love is the chaos of one person's war.
