Would send something in, but realistically my “chitchat” would be //avoiding all eye contact and hiding// (But, hey if you wanna work with that, then I’d request that for Akaashi, Akashi, or Kuroko)

*Kuroko notices your
furtive glances* 

“Akashi-kun,” he begins and both the setter and his former
captain look up from their books, “who is that?”

They look at you curiously,
Akaashi replying, “I think she goes to my school, or at least, has been to our
games before.”

“She looks…nice. Should we invited her to join us?” Akashi
asks.

“She looks pretty nervous, I wouldn’t want to make her feel
uncomfortable,” remarks Kuroko.

“I have an idea,” Akaashi comments, taking out a blank piece
of notebook paper and scribbling something down. He gives it to one of the
waitresses, asking her to deliver it to you and providing a tip for the
inconvenience.

When she approaches, you blush but take the paper reading, “Hello, I think we know each other from school but forgive my poor memory for not remembering your name. I’m Akaashi. Here’s my phone number, if you want to “chat”
with me or my friends, please reply. If not, it’s ok, we just hope you have a nice day.”

Your fingers nervously type in his number and a text message
of, “Thanks
for the note, my name is _____.”

The three boys take turns chatting with you, the basketball players also providing
their numbers for later conversations.
