Night Call Manga
After spending some time as a homeless drifter and casual rent boy, Asaoka Shino decided to join the police force's Zero Unit, an anti-terrorism division, to aid the fight against the rapidly growing terrorist problem. He has a real chance to join the unit as an undercover officer, but first he has to pass a highly-secretive test to see if he could be used in 'honeytrap' operations, which is to have sexual intercourse with an examiner. But the assigned examiner is male. Can Asaoka go through with it?
