Characters
Miharu Shimizu Male 7th Grade (1st year junior high) Born May 14th, Type O Usually the supportive one, but regresses to an infantile state when his mental health collapses. His bed has a body pillow and exactly one plushie. He absolutely hates the sweet scent of perfume. His family life has fallen apart, and he cannot trust any adults except Mitsuya. At school, he was subjected to indirect bullying and kept himself closed off. However, the Little Bird Room was created at school. There, he doesn't have to hide himself. Even when he's suffering, his friends and teacher stay by his side and support him. Because of this, Miharu considers this place more of a home than his actual house.
Chihiro Izumi Male 7th Grade (1st year junior high) Born August 7th, Type B He takes care of others, but he is the most likely to have a mental breakdown. He loves cute things, and his bed is covered in many plushies he brought from home. He is given only the necessities, but his existence is ignored. His parents pay for living expenses and tuition. He has a smartphone, and his basic living environment is maintained. Therefore, people around him think he is being "raised properly." However, his parents know almost nothing about his school life. They sometimes forget his birthday or school events. When he goes home, there isn't even a "welcome back." Even when he's sick, they don't take him to the hospital, so he has to manage on his own. Despite having a family, his life feels like living alone, just with a few more belongings.
Haruki Mitsuya Male 25 years old Born April 12th, Type O Good-looking. The teacher in charge of the three and a specialized support educator. He puts the three of them first and usually stays in the Little Bird Room with them in case anything happens.
