A Key and a Lock

"Well, classmate, I want to ask something." "Huh?" The girl tilted her head in confusion. "That's right, what shampoo did you use? It feels like your hair is very smooth, haha." The boy also felt that his question was a bit strange and couldn't help but laugh. She has short hair, and when she flicks it, it's as smooth as a horse's tail hair… This is the young man's recollection afterwards. After such a first conversation, he couldn't help but sigh that life is like a drama, but is the process important? It would be nice to have a happy ending!
