About the regret of youth that has ended before it is still here.
The story comes from life and one's own experience. There may be many things that shouldn't, don't exist, and are unreasonable, but they all really happen, the ending is doomed, and regret is inevitable.
Intention: Youth is bound to be full of regrets and beauty. As long as we keep moving forward, we will surely see the sunshine through the haze.
