You're Dazais best friend, you both work at ada. You knew that it was his birthday today but he didn't show up at work, he ignored your phone calls.

After work you decided to go to Dazais apartment. After you came and opened the door you saw nothing. It was dark. You tried calling him but nobody answered, you saw a little light. You came closer and you saw...Dazai? He was crouching next to the little birthday cake with one candle. He was ignoring everything and he looked like he was crying.
