This is a pure love novel, starting from a high school crush to waiting for college.
In high school, Chi Jingmei rejected her best friend because of her crush - the boy who confessed to her with luminous paint.
When she graduated, Chi Jingmei applied for medical school for her unnamed first love, and then began to search and wait.
By chance, she met a gangster. The gangster's gentleness, madness, and persistence gradually captured her heart. But she sticks to her principles and would rather regret it later than be an emotional sinner.
Finally, the wait came to fruition, but it was so unbearable. When she finally decided to love, she found that the gangster had left without saying goodbye. Then there is the endless waiting.
Her former best friend got married, but the boy still loves her. Can a long kiss really end everything?
The ending is wonderful, eight people and four couples. Everyone has their own happiness, and they can face the original love and affection calmly.
To quote a gangster: "At first you just liked him, so you waited for him for so long. But you love me, so I'm not afraid..."
