Wan! Chapter 46

Celebrating His Birthday (お誕生日を祝うのだ,) is the 46th chapter of the Bungo Stray Dogs Wan! manga.

Summary
Poe plays a detective game with Ranpo and is amazed that he and Ranpo are best friends. He quickly realizes that Ranpo's birthday is coming up, and as his best friend, he must celebrate.

Poe comes up with a plan to surprise Ranpo. First, he could invite Ranpo to play a detective game as always. He plans to give him a normal novel, and while Ranpo is reading it, he will surprise him with confetti. Next, he will sing Happy Birthday, and finally, he will take out a cake. He imagines Ranpo enjoying the cake and praising him.

On Ranpo's birthday, Poe decides to execute his plan. He goes to see Ranpo, but Ranpo is confused with the novel, wondering why it is titled Happy Birthday. He showers Ranpo with confetti, but Ranpo looks at the ribbons with confusion. Ranpo tells Poe to be quiet, as he would like to read a book. Poe tries to sing the Happy Birthday song, but his eerie singing voice confuses Ranpo further. Ranpo complains that he is being noisy, and if he keeps disturbing him, he will not play any detective games with him.

Poe takes out a cake and offers it to Ranpo, who smiles in excitement. He eats a strawberry off the cake and instructs Poe to leave it on his desk, designating the cake as a snack. Poe, depressed, apologizes and leaves the room, but Ranpo calls after him, complaining that the book he had written is boring. Poe explains that he wanted to celebrate Ranpo's birthday, but Ranpo tells him that his birthday is in autumn but it is summer. Poe had thought too intensely about planning for his birthday.

Poe apologizes again, but Ranpo asks him to stay and play detective games because he is lonely. Poe stays, and Ranpo tells him to surprise him in October next time.
