A relationship between people goes from being cautious and cautious at the beginning, to gradually being tolerant of each other, then to conflicts, indifference, and distance, until finally it is calm and peaceful. I finally got such a result, but there was nothing left. In the process, the freshness of the first meeting was worn away, the enthusiasm of getting along was worn away, and the relative torture was worn away. Time like this does not fill and heal, but grinds away and forgets all the scars. To this day, we are still the same person we were when we first met, but not anymore.
