The title of the story comes from the heroine. The original words are: "He is like a profound ink painting, written lightly, but never forgotten."
This is a story about teachers and students, a story about seven years, and a story about deep love.
You were born before I was born, but I was born before you were old.
You were sweating on the three-foot podium, while I was sitting in a corner of the classroom, staring at you.
