when they missed the last train to rome, yunhyeong had tugged her hand and pointed towards the monitor screens. she squinted her eyes before she saw what he did; the next train would still be heading for italy, to milan.    sana had her doubts, her hesitations, ever since they ran to the other side of the notre dame to head to the nearest taxi station to take them to the trains. in the time sana was studying here, she's only been outside of paris once. in lyon, with momo her roommate and some other students from la sorbonne.    she's never ever been outside of france, except for that time she went home during christmas a few weeks back. but that was it. rome? italy? milan? it would be her first time on a impromptu trip. she was nervous, yet, when yunhyeong gives her this look (soft eyes, soft smile, relaxed features) the nervousness is replaced with excitement.    and she finds herself saying, "okay."    the trip from paris to milan would be seven hours, shorter than it would be if it were rome. which is all the better. it's a night train but the cabins are all nearly empty, they sit on one with a table and sana sits near the window while yunhyeong drapes his jacket over her coat and he leans into her.    "is it okay if i sleep?"   sana smiles, nodding. "sure." he smiles back. "you do know that, when we arrive, you've been to three countries in the past twenty-four hours right?"    "right."   she pats his arm. "go to sleep."    sana watches the scenery change. from brick walls to vast valleys to tunnels made of steel. slowly, the night deepens and the skies are darker, looking more like black holes than anything else.    only when she slumps a little in her seat, when her head seems to be in between asleep and awake, does a slip of information enter her mind. a piece of information she should've remembered amongst everything else that was happening.    that's why she sits up straight, surprised, and that's why yunhyeong complains and pushes her back, rubbing the side of his face before leaning back on her.   "what is it?"   "nothing,"   and really, it was nothing.            milan was lovely, even at night. even when the streets were deserted. even when there were drunkards cursing at the sidewalks. even when the air was chilly. even when half of the city was asleep, and the other half, awake as ever in their own ways.    yawning, sana checks the time on her watch. "it's like what, one in the morning?" yunhyeong nods, burying his hands in the pockets of his coat. sana wishes he'd hold hers instead, but she follows his lead.    "so," he turns to her, eyes bright despite the cold. he sniffs, his nose is already red. "what do you want to do?"   "yun, look around, there's nothing much."   "there's a pub over there, but -" he looks at her, and he purses his lips. he nods. "yeah, not a very good idea. i forgot, you don't drink anymore. we can rent a place. we've already slept but... wow, i am so unplanned."   sana laughs. he looks at her, and the smile he has is something new - a mix of amusedment and embarrassment. well, they were here now. unplanned. impromptu. she didn't really know what to do, but she knew that they should at least make the best of it.    "come on, let's just check in at a motel or something." with their hands clasped together, they run through the streets of this european city, laughing, kicking at trash bins, disturbing the peace and earning a middle finger from one of the pedestrians they passed by while crossing the street.    "mi dispiace, signore!" sana shouts, covering after in a fit of giggles. she lets go of yunhyeong's hand and they both slow down. cold sweat ran down the side of their faces, they were laughing now. "god, we're awful."   "and we haven't found a single motel that's open right now." he laughs again. "you didn't tell me you knew italian."   she shrugs. they both walk side by side, yunhyeong's arm around her shoulders. his hand cold, like her's. "a little. i had a fling with an italian guy at class once."   he looked flustered. "wh - what?"    sana merely laughs again.            yunhyeong had money spilling out of his pockets, and that wasn't really an exaggeration. when he took his hands out from the p
