With a wave of your hand, our friendship collapsed in an instant, and our relationship was severed by you. Doesn't everything in the past count? Are all our efforts a lie? You said that we would keep going like this. You would accompany me and I would accompany you through this period of school days. But I didn't expect that the oath would leave us so quickly, let alone that we would fill our encounter with hurt. Everyone has experienced happy moods and sad emotions. However, when we are surrounded by endless sorrow, we should try our best to resolve the sorrow and troubles and compress the negative emotions caused by that mood to the minimum level.
