"It rained last night, and the weather will be nice again tomorrow" is the lyrics of which song?

The theme song of "Animation City" "Hurry up and tell you" Supplement: It rained all night, and when I woke up early, the weather was fine. I dreamed of you last night. Our happy games were all blamed on my carelessness. I blamed myself. I'm too careless to find your address, but my father is going to the post office and wants to tell you quickly. I drew a picture with the crayon you gave me and sent it to you by express. Tell you quickly that I care about you so much. No matter how far the journey is, it doesn't matter to me. My heart is with you. It rained all night. When I got up early, the weather was fine. I dreamed of you last night. Our happy games were all blamed on my carelessness. I blamed myself for being too careless and couldn't find your address. But my father had to go to the post office and wanted to hurry up. Come on, let me tell you how much I want to study 100,000 why questions together every day. Come on, let me tell you some truths. The most important thing between friends is friendship. My heart is with you
