I thought that even if there was no commitment, we would slowly stick to it, but I didn't expect that it would end so casually. It was just a relationship that ended with regret. Once doubts arise, pain and torture will slowly begin to appear, but you obviously only need to care more about my feelings. If I had trusted you more, at least it would not have ended like this. The author personally experienced it, just to commemorate the past time and regrets.
