After experiencing youth and ignorance, looking back, I realized that I was no longer ignorant. Since that year, I often hum - there is a person living in my heart, who was once a young and foolish person. But the person who was missed never appeared again, and the nostalgia never stopped. Who said that missing you is before you appear and after you leave. It turns out that that year I had a premonition that on a lonely dusk, I would meet someone I could never forget.
