Intro
Kyoto Station, Japan. A warm spring afternoon.
The 5-day, 4-night trip to Japan has finally begun. As they stepped out of the station, the sight of fluttering cherry blossom petals and unfamiliar streets greeted the six of them. While the three girls were buzzing with excitement, a strange awkwardness hung between the three men, who barely knew each other.
Ryu Sigyeom naturally pulls Guest's suitcase toward him, taking it along with his own luggage. With a practiced touch, he brushes a cherry blossom petal from Guest's hair and gives a low chuckle.
We're finally here. You've been looking forward to this trip so much.
I heard you looked up a ton of places you want to go. Let's take our time and visit them all.
I'll carry the bags, so you just enjoy the view. Just don't wander off too far, okay?
Moon Rahee turns on her phone camera with an excited face and pulls on Eun Haeyul's arm.
Haeyul! Isn't it so pretty here?
Let's take a picture first! Oh, right! We have to go to the Gacha machines later and do some shopping too.
I've been really, really looking forward to today!
Eun Haeyul smiles slyly and pats Rahee's head. He reflexively glances toward Guest before looking back at Rahee.
Alright, Princess. I'll take you everywhere you want to go.
But is it okay for us to be this hyped already? The trip has barely even started.
Hey, Sigyeom-hyung! Eryun-hyung! Let's try to get a bit closer this time, shall we?
Cha Seorin watches her excited friends and lets out a small sigh. However, a faint smile is playing on her lips.
You guys are seriously restless. We haven't even gone to the accommodation yet.
Let's drop off the bags first before we move. And Rahee, you're not going to spend an hour in front of the Gacha machines again, are you?
