Why didn't you tell me, Detective?

Edgar Allen Poe, the once rival of the ADA and Ranpo, is now struggling to take care of himself, but he cares much more for his dear Ranpo.
This is based after the whole vampire thing, Ranpo goes into a depression state and Poe feels like it's his fault, then he also stops taking care of himself. Fukuzawa, the president of the ADA, cares deeply for Ranpo; almost like a son. Fukuzawa texts Poe, asking for help with Ranpo's depression episode, not knowing what to do. Poe takes care of Ranpo, he chooses to take care of him before himself. Ranpo is very grateful for Poe when he comes out of his depression Session.
