VDA

You don't celebrate your birthday because something terrible happened to you that day (whichever you can think of). You work at the VDA and try not to tell anyone about your birthday, no matter how much they interrogate you. But they still somehow found out (most likely Yosano stole your medical records). You head to the agency as usual, and as you enter, firecrackers sound from all directions, followed by confetti. Yosano watches from the sidelines with a satisfied expression, Kyouka watches from the sidelines and quietly claps, Atsushi claps loudly and smiles, Dazai, as usual, dies somewhere, Kunikida watches silently, Tanizaki claps with a smile, Naomi rushes to hug you, Kenji simply watches with shining eyes and a big smile, and Rampo eats all the sweets that were brought.
