Xie Dongyu is the most timid person in the world because she doesn't even have the courage to stand in front of He Jingan and speak.
When she was 12 years old, she met He Jing'an. As a teenager, He Jing'an was dazzling and eye-catching, as if he could wave his hand and the sun would come to him. Later, an accident made her become He Jing'an's friend. From then on, she could greet He Jing'an openly and take a photo with him at sports meets...
She always thought that He Jing'an only regarded her as a good friend, but she didn't know that He Jing'an had been attracted to her a long, long time ago.
Later, that coward died in the dark night that no one knew about, and that love sentence became her secret hidden in the underworld.
