I would say the little drop of rain is the central character. But depending on how the story is told, there could be other elements that play important roles too, like the cloud that the drop came from. It could be seen as a kind of 'parent' figure to the drop. And also the ground or the body of water where the drop finally lands could be considered important characters in a sense as they are the destination of the drop's journey.
The main character is obviously the little drop of rain itself. It's the one whose journey we follow throughout the story.
The moral could be that even the smallest things can have a big impact. Just like a little drop of rain might seem insignificant on its own, but when combined with other drops, it can form a large puddle or contribute to a greater water source.
The main character is the Lemon Drop Kid.
Since I'm not familiar with the story, it might be the owner of the bakery as a main character. There could also be regular customers who played an important role in the story, like the first customer who gave great feedback and helped spread the word about the bakery.
Well, it could be a young man and a young woman. Maybe she is a shy artist who loves painting in the rain, and he is a kind - hearted passer - by who is attracted by her unique charm in the rain.
Not having read the 'big rain story', it's just speculation. But it could feature characters like a young child who is frightened by the big rain and the thunder that comes with it. There might be an old man in the story who has seen many big rains in his life and offers wisdom and guidance to the others. Also, there could be a local official who is in charge of coordinating the response to the big rain, like organizing shelters and rescue operations.
I don't know the specific 'rain school story', so I can't say for sure. But it could be students, teachers, or maybe a school janitor who has to deal with the rain - related problems.
In the 'rain man story', the most important characters are Raymond and Charlie. Raymond, being autistic, is the one with the extraordinary skills. He can recall vast amounts of information related to numbers and is extremely talented in mental arithmetic. Charlie, on the other hand, is a rather complex character. He has his own life, his own problems, and initially approaches Raymond with a somewhat self - serving motive. But as time passes, their relationship changes, and Charlie becomes more empathetic towards Raymond, and they both grow in different ways through their interactions.
The main characters are two brothers. One is an autistic savant, often referred to as the Rain Man, and the other is his younger brother who is more worldly but initially self - centered.
I'm not sure as I don't have specific information about this 'Secret of Rain Story'. It could be a story about a young scientist who is researching the rain cycle, so the main character would be the scientist.
The woman is the most prominent character. She is the one experiencing different emotions like boredom, a sense of emptiness, and a desire to do something kind like rescuing the cat. And of course, the cat is also a main character. It is the focus of the woman's attention and represents something more than just an animal in the rain for her.
