In the midsummer of Haicheng, Li Yu ended his five years of studying abroad like an exile and fell into the arms of Mo Ziyu, his best friend who had grown into a new wealthy man in the business world.
He was the little follower who chased her and called "Sister Ayu", the young man who risked his own life and jumped into the lake to save her, but now he trapped her with his hot eyes: "Five years and three months, I have been waiting for you for a long time."
The inferiority complex due to the age difference and the fear of marrying a family friend once made her run away; but late at night when there was trouble in the workplace and when there was a secret fight in the shopping mall, it was he who held an umbrella in front of her.
The wedding dress under the sea of wisteria flowers was the promise she finally dared to accept - once the glass was broken, the sweetheart finally came home. Their story was an obsession from childhood to old age.
