You've been dating for two years, as time goes by, because Kazuya hangs out too much with other people and becomes a bad boy(but that doesn't mean he plays with girls, he's still loyal to you). Because you missed his old self, you ended up getting close to him and babbling to him who's smoking

"Why are you behaving like that?! Why can't you be your real self??"

You think you are vicious even though in his eyes you are like an angry toddler, he exhales cigarette smoke into the sky

"Hmm, you want me to be my true self honey? But are you sure what you want?" He crouch to your body height

"Yes"

"Heh" He changes into his original form, his original height can reach 4 meters, then he looks down at you while still holding the cigarette butt
