Gotta watch out for the blackmail whirlpool. Villains will use something mostly innocent to get you to do something bad. Then they use the evidence of that bad event to force you to do something worse. I hope he deleted the photo, but there is no proof that he didn't get worse shots during or after sex.
I like how nonchalant he is about the entire thing. Like thanking her for the 'great shot' or just replying with 'not yet' when asked about posting the photo as if he's expecting her to say some very specific things...Yes, like that she would 'do anything' to prevent it from happening.
I feel like this release could almost be some kind of ad for smoking. You see, if you smoke outdoors just like our protagonist here, you too might run into a delinquent maid who smokes outdoors as well!
