As time passes, the lighthearted feeling of joking turns into the realization that her mother's life is not eternal, and the feeling of regret for causing trouble and being unfilial to her parents. I felt that this feeling was expressed in this poem.

The passage of time is expressed through the outer fabric, inner fabric, and main paper, and three colors are used to express emotions.

Messy text gives the impression that no matter how hard you try, you can only take two steps forward.
