Minseok and Jongdae meet on a train. Jongdae is pretty forward, but Minseok is already taken. 
Sooner or later they become friends, and sooner or later Jongdae really starts to fall. 
But Minseok has a girlfriend, so that kinda .

Minseok looked at his phone and checked the time, only lessening his mood as it turns out he hadn’t even been on the train for two minutes.  Sighing, he mindlessly scrolled up and down his Facebook feed, until after what could have been a few seconds or minutes the train harshly swerved, and all of a sudden he found himself pushed up against the walls of the train with two hands either side of his face. Minseok followed the line of the arms and finally came to the owner of said hands, and what he noticed was that this guy had the most amazing jawline and was staring at him with a certain expression that he couldn’t quite comprehend.

Now, standing this close to a random stranger was nice and all, but Minseok felt quite awkward with the way that this guy was looking at him, especially as he had been doing it for a good 20 seconds. “Uhh - are you going to-,” Minseok stuttered, feeling nervous under the constant stare, “…Move your arms?”

The man snapped out of his reverie and smiled what could have been the most beautiful smile Minseok had ever seen. “Oh, sorry about that, the train turned and I wasn’t stable enough. Then I just got caught up looking at your face. Good job on that one. Ten out of ten for genetics.”

Minseok looked at him awkwardly, “You’re quite forward, don’t you think?”

The stranger smirked, “Well, what’s the use of talking in riddles?  I might as well tell you what’s on my mind – I mean it’s not like you didn’t notice me staring anyway.”

Minseok stood there, a slight blush covering his cheeks – he never could take compliments well, “Didn’t you ever learn it was rude to stare?”

The stranger continued to smirk, “But shouldn’t we appreciate the finer things in life?”

Minseok laughed, mainly out of embarrassment, “You don’t even know my name.”

“But a name is just a word, is it not?”

“It’s a pretty important one though, isn’t it?”

The stranger stood in thought, before nodding, “You have a point... So tell me; what is it?”

Minseok rolled his eyes. “It’s Minseok, and yours? It’d be nice to whether my girlfriend murders you after she finds out about this, what if I don’t have a TV nearby?”

Stranger’s eyes widened, before laughing, “My names Jongdae, but you’re taken? Damn... Since when?”

Minseok went over the name in his head before he’d registered what he had said. Said creepy stranger with the name Jongdae was sad he was taken, what is this? “Since last week, actually,” he said smiling, he had been pining over this girl for weeks, and in the end he didn’t even have to ask her out because she did it.

Jongdae frowned before smiling, “Damn, I just missed out, didn’t I?”

“Guess you did,” Minseok shrugged. He was into guys too. “but I’ve liked her for a while, so I don’t even know.”

“Well she must be pretty lucky then, for you to like her.”

Minseok grinned, “Oh but I’m the lucky one. She’s SNSD quality.”

Jongdae gasped, “Wow, I’ve got no chance.”
