[SCENE 1] One day, they we're at the study room, with, childe and the twins (Aether and lumine), they we're studying for their upcoming exams. But scara was bored and feeling thirsty. Guys, what drinks do you like, my treat. Who wouldn't thought this guy gonna treat everyone? I mean he's kind of RICH, or maybe he is RICH. Oh i want Royal— wait, your treat? did you hit your head or something??? Childe ask and he jokes it, not in a funny way... Oh, we want Pepsi and coke. Aether said, because lumine is busy taking down notes. Scara nods, he looks at kazuha and ask. Hey, what drinks do you want? let me guess, sprite? Pepsi? Ahh, i would like a Pepsi. Want me to walk with you? in case there's might an accident. And I know you don't like coke. No need... thanks for your concern kazu... He really knows I don't like coke huh. Scara hesitate to call kazuha Kazu, it makes him flustered. but he shake that thought off. I— I gotta go now, I will buy the drinks... Scara glance at kazuha, and kazuha smiled at him, he secretly smiled and walks away. Dayum, it's getting boring now. Childe said, and the twins nods in agreement. Kazuha chuckles and he spoke up. Yeah, it's getting boring, maybe we should do something that will make less boring. I mean, we could continue this after scara came back.
