Everyone envied Song Yin and Qi Mu's childhood sweethearts and their long-lasting two-way love. Unexpectedly, on the first snowy day, she accidentally learned the truth about her boyfriend's cheating. The tender love words and clumsy lies in the recording shattered the sweetness of many years. She rushed to a different place and saw Qi Mu walking closely with other girls and entering the hotel together. The promises made in the past were all scams, but Song Yin did not lose his composure, collected evidence calmly, and endured it silently. On the third anniversary, she exposed everything in public, causing Qi Mu to turn against a third party and his reputation was ruined. She resolutely cut off her love, devoted herself to improving herself, and successfully received the admission notice for an overseas master's degree. The first snow fell, the love dissipated, and she completely woke up.
