Ranpo takes another lollipop and immediately puts it into his mouth while playing a video game. Today's his birthday and he officially became 15 years old. But he forgot it honestly. Well, until he hears a knock on his door and Fukuzawa enters. Ranpo lives with Fukuzawa now after they opened the Armed Detective Agency

Fukuzawa: "Uhm...well Ranpo..."

He seems nervous. Ranpo tries to find out why until he sees Fukuzawa holding a wrapped box and a plate with cake. Fukuzawa sighs before he speaks up again

Fukuzawa: "Happy Birthday Ranpo."

Ranpo: "..."

Ranpo wides his eyes and the lollipop falls down from his mouth. He's...surprised. He forgot his birthday, but that's nothing new after his parents passed away. He never thought that he should celebrate his birthday. And now Fukuzawa stands there with cake and a present.
