When that still doesn't help, he goes out after work to drink away his sorrow and is approached by an incredibly handsome man. Happy to have some company, Kaoru drinks until he passes out... The next morning, he wakes up in a hotel room in bed with the man from the night before and finds the guy took photos of Kaoru wearing the bra! And now Kaoru's getting blackmailed into doing all sorts of things...!
