The experiences before the age of 23 seemed to be for the meeting at the age of 23. Two life trajectories that seemed to have no intersection suddenly met, intertwined, and entangled... There is a saying: Looking back, it is marriage; passing by, it is destiny. The girl who said "I don't know" didn't know if she really didn't know, and the boy who "won't tell" didn't know why he didn't say it. Just like this, we struggled, experienced, laughed and cried together, and walked a long road hand in hand. Later, the road was too long, and they broke up while walking... Stumbling, looking back, it was still the "best encounter".
