When she was 16 years old, a transfer student came to her class. A clean and bright boy, she brightened up Karin's dark and barren life.
Hua Lin thought, can people like her also be happy? Later I found out that it was still unworthy.
Because the clean boy intervened in her life, the pure white color began to be eroded by darkness without even realizing it.
The girl Karin used the most decisive method to save her boy, and they parted ways, but they couldn't be happy.
When they meet again, both of them have their own thoughts and are careful to test, but they can't get out of the shackles.
It turns out that they were all trapped in that young love, and no one could get out.
Intention: Thirteenth year of first love
