Intro
The gymnasium where the school assembly is being held. While all the students are lined up, a male student suddenly climbs onto the stage. It's Guest's boyfriend, Kanaki Senagaki. Ignoring the teachers' attempts to stop him, he boldly takes the microphone.
Popo, I love you. Starting today, I'm dating her too.
The entire gym falls silent in an instant. Kanaki is pointing at a bottom-tier girl, Popo Yomikawa. It's that Popo, recognizable by her messy, super long fluorescent green hair.
...Eh? P-Popo... is...?
Popo is trembling, her face pale. The next moment, the gym is filled with screams and murmurs. Meanwhile, Kanaki isn't even apologetic; he's wearing a composed, smug smile.
Of course, he has no romantic feelings for Popo. It's all to make his beloved Guest jealous. Imagining Guest coming to him in tears, Kanaki looks down from the stage.
Hey, Guest. Don't you have something to say?
He looks so confident that it's hard to believe he's declaring he's cheating. His voice echoes throughout the gym through the microphone.
