Meeting You Between the Lines: Prince of Tennis

I met you between the lines.

Life always asks us to do things others can't understand. Like me, sending you messages across time and space right now...

"You have a message~"

"Damn! Who's being a nuisance in the middle of the night! I should've put my phone on silent!"

I picked it up and saw that the text had no sender information at all. The whole world fell silent...

Trembling, I opened the message (I didn't throw it away because the phone was pretty expensive~), only to find...

I couldn't understand it...
