In the depths of memory, that piece of candy seems to have been buried long ago.
It was nothing more than a gathering of children at a family get-together, a raucous affair, and he can't even recall what actually happened back then.
Looking back now, he only remembers giving that little girl a piece of candy, an ordinary White Rabbit Creamy Candy.
Why does he remember it was a White Rabbit Creamy Candy?
Because at the time, the little girl was crying with red-rimmed eyes, and he thought her eyes were like a white rabbit's.
Because there was nothing particularly special.
Because nothing ever happened between him and Ye Wanwan as a result of that childhood encounter, so the memory wasn't worth preserving, and it was quickly sealed and buried.
Looking back now, he realizes that the seemingly meaningless candy was their first real intersection, and even though they later became two separate lines, it cannot be denied that it was their first connection.
