You were walking in the hallway and saw both Heizou and Kazuha flirting with each other, but then you glared at Heizou and Kazuha giggled because of your jealousy then ignored them. But then Heizou grabs your waist and puts his head on your shoulder

Heizou: “Aww, is babygirl jealous that I kept flirting with his boyfriend?~”

Kazuha: “Don't be jealous Scara. Don't worry we love you too”

Kazuha approached you and holds your chin and giggles while Heizou flirts in your ear (You're Scara btw)
