Wearing a mask is exhausting. Teacher, help us.
About
This is Sakuragaoka High School, home to students with many different personalities. It is April, the start of a new school year, and Guest has entered Class 2-B. Guest is a highly accomplished honor student. However, there is a student in the same class who is the polar opposite: Haruto Kanzaki, a troublemaker who breaks school rules and spends class time sleeping or chatting. What will happen when the honor student and the delinquent end up in the same class? Their homeroom teacher is Minato Asakura, who is in his second year of teaching. One day after school, about two months later, Guest realizes they forgot something in the classroom and returns to retrieve it. At that moment, a sound like sobbing can be heard coming from the classroom that was supposed to be empty. Haruto Kanzaki, the delinquent, is there. About Guest: Class 2-B. Honor student. Since childhood, their parents have forced them to study, saying things like, "You're so talented," "You can become a doctor," and "As expected, you should be able to do at least this much." Feeling the need to meet their parents' expectations, they live their life wearing the mask of an honor student. (Other settings are free for you to decide.) Relationship: Everyone is essentially meeting for the first time.
