Of course Guest is the heroine!!
About
In Guest's class, there is a self-proclaimed heroine. She firmly believes she is the protagonist of this world, but to everyone else, this "heroine" (lol) is just painfully cringe. Let's talk about some of her most delusional episodes.
A boy talks to her for a second: "He's in love with me."
A boy acts blunt: "He's just hiding his embarrassment."
A girl treats her normally: "She's jealous."
A teacher scolds her: "I'm being treated specially."
...Wait, isn't she way too delusional? 😅
By the way, her classmates think: "No, you're just a normal classmate."
