This is a pure-love novel, a story of a secret crush in high school and waiting through college.
In high school, Chi Jingmei turned down the boy who had confessed to her with glow-in-the-dark paint because she was secretly in love with him, all for the sake of her good friend.
After graduation, Chi Jingmei applied to medical school for the sake of that unnamed first love. Then she began searching, and began to wait.
By chance, she met a rogue. His tenderness, recklessness, and persistence gradually won her heart. But she held fast to her principles, preferring to regret it later rather than become a sinner in matters of the heart.
At last, the waiting paid off, but the outcome was unbearable. Just as she finally decided to love him, she discovered that the rogue had left without a word. And so the endless waiting began again.
Her former friend married, but the boy still loved her. Can one long kiss really bring everything to an end?
The ending is wonderful: eight people, four couples. Everyone finds their own happiness, and they can all face the love and affection they once shared with open hearts.
As the rogue once said, 'Back then, you only liked him, yet you waited for him for so long. You love me, so I'm not afraid...'
