Author's note: So the 'at' sign doesn't seem to appear in the story! which is very weird since it is integral to Twitter hmmm. I have nevertheless replaced the 'at' sign with the '&' sign, for symbolism's sake!

Lesson 1: Choosing a Username

After a quick crash course on the merits of Twitter, So Yi Jeong, self-proclaimed Twitter skeptic, was almost convinced as to why he should bare his soul in 140 characters. There was only one thing he didn't understand.

"But why can't I use 'Casanova' as my username?"

"Because, pabo," a miffed Woo Bin sighed, having to explain it for the fiftieth time, "You're not the only one in the whole wide world who thinks he's 'all that'. Like, just about every other guy on Twitter thinks he's Casanova. Just that you're not the first and fastest to get that username."

As Woo Bin turned his attention back to his phone, Yi Jeong stared at the homepage displayed on the computer screen, thinking hard.

Yi Jeong blinked as he processed Ji Hoo's statement, and winced as he felt a smack on the side of his head.

"Nice going, Casanova. Nice going."

Surely there's a way around this… Yi Jeong pouted for the second time that hour, and rubbed the side of his head.

Woo Bin smiled and started typing a reply into his phone.

F4DonJuan &F4Casanova – much better. You would have saved the other guy the hassle of being suspended if you weren't so... insistent.

"Well, if you had told me the F4 had a protocol when it came to usernames, maybe I wouldn't have done that!" Yi Jeong yelled from across the room.

Woo Bin threw his hands up in defense as he walked over to his Twitégé (aka Twitter protégé). "Hey, hey, chill man. You can change it anytime you don't like it, okay? Don't sweat it. Now, let's get you to the next step. Following people…"
