It tells the story of the cold-tempered Xia Tian, who met the young designer Jiang Yi in a bridal shop when she was preparing to get engaged with her boyfriend Chen Mo, who was considered a "perfect fit" by everyone. Behind this seemingly logical engagement, there are already hidden cracks - Chen Mo's frequent missed appointments, the secrets in his mobile phone, and the smell of perfume that is not summer, are all quietly tearing apart his gentle and considerate mask.
Xia Tian was far from passionate about this relationship. When he accepted Chen Mo's pursuit, it was more of a surrender to "suitable" public opinion and his years of persistence. Until she discovered clues about Chen Mo's derailment, she did not break down and cry. Instead, she calmly collected evidence and determined to uncover this carefully crafted scam with her own hands.
At the engagement party, Xia Tian revealed the truth in public. Chen Mo, who was so angry that he almost became violent, was stopped in time by Jiang Yi who happened to send the design drawings. This designer, who is six years younger than her, became an unexpected support for her in her embarrassing moment with his professional acumen and silent kindness.
The crack under the skirt is the exposure of lies and the beginning of new life. When the dream of "suitability" was shattered, Xia Tian finally saw her own heart clearly, and the dress designed for the engagement may be waiting for its truly bright moment of glory.
