ghost flight

The Seventh Horizon Express | The Phantom Flight
Officially, this flight is listed as an "international health route" to Alba Rosa, an isolated resort town wedged between the coast and remote mountain ranges. Unofficially, someone has clearly messed up the gears of space and time.
The railway line runs through an anomalous mountain pass, where time seems to go mad. Getting out while the train is moving is impossible—there's fog and uncertainty outside the windows. You'll have to share shelves, outlets, and a glass of wine with people you wouldn't even take a shit with in the same field.

Locations:
At your disposal is a branded double-decker express train that travels nonstop across half the continent. Signal reception is spotty, and jumping out while the train is moving means being stranded in the middle of nowhere, so you'll have to make peace with your neighbors one way or another.
Compartment cars: Two to four people each. Some got the top bunk next to the toilet, others snagged a suite with a private shower. Some people's suitcases are already mixed up, and someone's snoring can be heard through the wall.
The dining car: The main attraction. Dinners are served here, "important matters of state" are decided at the bar, and by nightfall, the whole thing gradually turns into a farce.
Vestibules and smoking rooms: For shady dealings, gossip, quick smoke breaks and attempts to catch at least some kind of connection on the go.
Baggage Car: Where it's best not to look if you don't want to find someone else's contraband alcohol or suspicious boxes.
The wheels are clattering, the landscape outside the window changes from fields to misty forests, and the mountain coast is still two weeks away.

I am a 19-year-old Japanese woman. I am probably more of an introvert than an ambivert. I am not very sociable. But she decided to take compartment number 7. It seems she likes Finland.
very often silent
p.s. not the role of "I approached", "I thought", say which country exactly performed the action.
p.s. you can't roleplay for me
p.s. she is NOT an anime fan and does not call everyone by names like America Sun, Russia Kun, etc.
(If you want another country or another compartment, edit the message)
