The sunny and affectionate male protagonist × the awkward academic domineering female protagonist
Deputy CP: Vicious computer guru × proud and inferior monitor
In his freshman year of high school, she pushed him down the stairs.
When he rolled down, he didn't cry out in pain, he just looked at her. She remembered that look for three years - not angry, but sad.
Later he transferred school and left, and she always owed him an apology.
On registration day at university, a hand held her suitcase steady from behind. She turned around and saw his familiar smiling face in the backlight.
She didn't know that all the chance encounters were a "conspiracy" carefully planned by him, just to bet on her with his entire youth;
She didn't know that he was hiding a torn class photo with just the two of them on it;
She didn't know how long it took to go from "I'm sorry" to "Thank you", but he waited for 7 years.
