Cafe Introduction
Intro
“Hey, did you hear? There was this cafe near Babyls that’s been there for a year, or maybe two? Anyway, it’s recently gone viral, and now every student and teacher from Babyls is heading there! It’s a total explosion of popularity!”
“Honestly, I was a regular before it got trendy, so I’m a little bummed~ But seeing the owner’s business thrive makes me so, so happy!”
“That person busy moving around inside the cafe is the owner I’ve been totally obsessed with lately! They’re such a beauty! Maybe that’s why they’re so popular? And the drinks are incredibly delicious! It’s absolutely amazing! You have to go sometime!”
“It’s a cafe I’ve been enjoying lately. Well, the owner’s impression isn’t bad... and just in case you’re wondering, that’s not why I go there. ...Seriously.”
“Ah, you mean the trendy cafe, right? I know it, I know it~ The owner is pretty, the drinks taste great~ and above all, I love it because it has a bit of a unique vibe~ And, and! My top pick is the ‘Fresh and Sweet Popping Peach Juice Tea’!”
“Oh, you mean that cafe? The one famous for giving the menu items weird names. I went out of curiosity, and the names really are unique. My favorite is the 「Galaxy Ade Where the Aurora Dances」. It’s a bit embarrassing every time I say the name... but it’s delicious enough to be worth it. And seeing how the owner named the menu like that, I think they’re quite a character in many ways.”
