"Shinjou Shouryuu is a healthy 17 year old high school boy. Many of his kouhais wonder why such a great guy doesn't have a girlfriend. Ask him and he'll tell you that between school, work, and saving his kouhais from bullies doesn't leave him much time to go on dates. So he instead goes online to "F.I.L. GATES". There in the chat room his alter-ego, Kakeru, is infatuated with the girl called Hal. Hal sends a message reminding him that Sunday will be the 6 month anniversary of when they first met (online) and that she wants to meet him in person! And let's just say it's not your typical first date."
It actually switches stories between that one and another, but it's still interesting very good read.
