It never makes sense to meet. The innocent and naive little black cat met Maize, the orangutan, and He Ershao at the simplest age. They laughed together, were sad together, and worked hard together... It was not spectacular, but it was enough to remember for a lifetime. However, the summer when the sunflowers bloom will eventually pass, and the leaves and flowers will eventually wither, leaving no way to care for them. There will always be imperfections behind adults. The naive and innocent little black cat will grow up, and so will the corn and the orangutan. Where can we find simple and eternal companionship? Where is the constant protection? We all missed it, but, but, we can never go back.
