The case in episode 6 involved a religious cult under the disguise of a counciling center. The purpose of the religious cult was to drug its members to use them for sex, which was suppose to "purify" their dirty souls. Episode 7 involved a girl who liked to swindle men for money. She became a swindler after her and her boyfriend broke up, leading to him becoming rich and famous. Episode 6 I thought was ok, but episode 7 proved to be pretty interesting. Some small elements related to the plot were revealed. One of Totsuka and Erika's ex-comrads, Inukai, appeared in episode 6. Inukai will also be in episode 8, possibly revealing some of Erika's past. Meanwhile, at the end of episode 7, Totsuka gave money to an unknown woman. There seems to be something that Totsuka is hiding. Overall, this drama seems pretty interesting.
