didn't that neighbor (ruslav?) show to banu pics of kamil cheating her?
There is no neighbour called Ruslav. The neighbour is Ahmed, the policeman, and he doesn't show Banu any pics. That's Murat. He attempts to set Kamil up. By having his ex-girlfriend, Humay, invite him to her apartment, on the pretext of helping her find a new apartment (since Kamil works in real estate). She then tries to seduce him, but Kamil rejects her advances, not realising that she's filming everything. Later, it's revealed that Humay is now actually one of Murat's fucktoys, and he manipulates the photos she's secretly taken of her meeting with Kamil, to make it appear that Kamil cheated on Banu. And the player then gets to decide if Banu believes it or not.
