There will always be someone who will stab you in the past because of youth and frivolity. Maybe it is an unintentional mistake, but you can only watch the wound erode and scab, thinking that it is healed. But you never know, in fact, in the time of reincarnation, one day, it will be bloody and torn open, ferociously laughing at your cowardice and youthfulness. From then on, it is rare to have deep love.
In the passing years, time will take away everything that is insignificant, and you will eventually forget it, but I can't express anything.
