The heroine went to high school in 2016 + was confessed by the boy she liked in high school in 2020 + she has always missed her high school life + fell asleep while looking through the photo album that evening... When she was woken up, she returned to that classroom + the sky outside was pink and purple + that beautiful moment that I never got tired of when I was a student + but had no chance to take a photo with my mobile phone + appeared again and again in my dream...
Intention: It's just a dream to go back to high school, wandering between dreams and reality. But in the end, dreams are dreams and reality is reality. We can't change it.
