In elementary school, Cheng tide played a game on the computer to test the fate between "she and him". For some reason, Cheng tide entered the name "Cai Yu" and the answer was 50%, failing. But I don't know when, Cai Yu's look at Cheng Xi touched Cheng Xi, and she also silently had him in Cheng tide's heart.
Whether it was fate or destiny, she was in his school in elementary school, junior high school, high school and even university, but he only knew that there was such a "sister", but he never knew her feelings. . . . . .
Concept: Fate is wonderful. It pulls one person but indulges the other.
