Okay so in the characters’ songs the characters that the song isn’t focusing on are used for backup as different roles; they all seem to be unaware of this, as they’re different characters then, except for after Noel’s Lament where Constance says “I liked the part where the two boys kissed!” and Mischa responds “What? In my country it is natural for two men to show affection by kiss-“ seeming like he was (the only one) aware of the fact he was in the song, perhaps not as another character but as… himself 👾
This is why Nischa is Nischa must I explain further
