[DeepL Translation - needs review] My niiichan is a crybaby. He cries easily when he gets angry, when he gets curry on his shirt, or even when he sees me getting an injection. I wish he was strong, cool, funny, and so much fun... What did Niichan do for me when I caught a cold on the day of our much-anticipated field trip to the zoo? What did Nii-chan do for me? This is a heartwarming story that touches on the feelings of children.
