@MothproofAcorn plot twist, she didn't send those recordings to the police or the scammer, but straight to the Yakuza instead and the scammers turned themselves in to avoid the Yakuza.
@feha Baa-san (? idk her name) knew it was a scammer but still offered the money and to talk because she knew he was having a tough time. That made him have a change of heart because of her kindness despite him trying to scam her.
