Expect the Unexpected [Oneshot]

Title: Expect the Unexpected
Fandom: Sexy Zone
Pairing: Sou/Marius
Rating: PG-15
Wordcount: 3900
Warnings: AU, underage (if this goes as it)
Summary: Sou wonders where the other passengers around him are going, considers who they could be since looking at people is about all he can do to entertain himself right now.

Notes: Look at me ticking off the therapy fics. I should start having these "time passed since idea: 9 years" and "time passed since fic was started: 6 months" since I take so long with some things lol. I've had the idea of people meeting on a delayed train since I first travelled far on my own by train and there was all the troubles there could be, and a foreign guy leaned over to ask the girl next to him what was said, and they ended up talking the remaning 3 hours. And. These two felt good for it.
I also wanted to write something a bit carefree, since it's pretty much out of my comfort zone lol.
(And I know I know, you can't write anything past G about Marius, but boy's 17 in two weeks, this should be okay.)
