When you are seventeen or eighteen years old, you are ignorant in high school, and the most important college entrance examination, when all these are intertwined, what a joyful and sad story it will be. Maybe it was an unintentional word that ignited a vague admiration in the heart, or maybe it was a small inadvertent action that was enough to make people see each other's trust and dependence. Some words don't need to be said, they are already known to each other, so why expose them and just let them be buried in the bottom of my heart like this? You like me, I like you, you are not allowed to express it, that's enough. There are too many past events to recall, too many what-ifs, maybe, this is not necessary at all, miss it, cherish it? It was all your choice at that time. You are no longer the same person as you were before. You no longer have the desperate attitude in the past. What can you regret? Only in this way can you remember it hard and have fun.
