Tengoku to Jigoku: Psychona futari (EP6) (Patreon)

A letter like a love letter that Hidaka keeps with him.

Ayako suspect that the sender of the letter may be a clue to the case, and asks the secretary, Juri, and Hidaka's sister, Yuuna, if they have any ideas about Hidaka's past. At the same time, Kawahara is questioning a witness who testified in a case three years ago that started a series of murders, which leads him to a suspicious person. Meanwhile, Yamaki is offered a plea deal by Tsukumo, who had arrested him for gambling. According to Tsukumo, the days when Hidaka kills people have one thing in common. 

Who will be the next target? Ayako has an idea that might give her a clue, and asks Riku for his help...

Wrong position of words in some lines:

0:44:21.85 to 0:44:32.36 (below is the correct wording. Updated the sub file as well.)
I told him about a customer with amnesia
who came in the other day, and I showed him your picture,
and he said he'd seen you here before and talked to you.
