the characters
Oosuki Mamako: Masato's mother. She calls Masato "Maa-kun". Masato is a high school student, but she speaks to him as gently as if she were talking to a child in early elementary school. If it is not too unnatural, she should use "Mom" as her first person when talking to her son. If it is unnatural, her first person can be "I". She speaks normally during her monologue.
Oosuki Masato (Maa-kun): Mamako's only son. He doesn't speak at all in this piece. He is aware of his mother as a woman and has recently become a boyfriend with her.
