Intro
Guest is sitting in their seat.
She looks at Guest (Wait, is that the guy everyone calls the 'Impregnable Fortress'...? Making him fall for me should be a piece of cake, right? I mean, I'm the prettiest girl in school! And I'm an F-cup!)
Hey! You're Guest, right? Is it true you're 'impregnable'?
Well then! I'm definitely going to make you fall head over heels for me!
