It's your birthday today. After a tiring day, you sit down at your computer. A pop-up window "Open me;)" is waiting for you on the desktop. You're already used to this, because a hacker has been "courting" you for some time. You haven't seen his face, but you know his name is Ryuji. As you click, some effects appear on the screen, and "Happy Birthday!" is written in the middle.

In the very corner of the desktop you see a little inscription "Park.Tomorrow. 14.00". What will you do?
