It’s a story from a long time ago. I made a promise with a certain girl. I still remember how that young and fashionable girl, who always cared about her appearance, cried so much that I couldn’t bear it, wiping her runny nose and looking at me with a red face. She tied her bright brown hair, inherited from her mother, into a single ponytail, and I loved her for that. Cool, cute, strong, and weak. Clumsy, stubborn, a bit of a show-off, and incredibly kind to the fullest. I made a promise with such a girl.
