do you know this anime?

Theres a population control shot you get when you graduate hs. its like 1/10000000 kills you when you turn 18 or something along those lines. i think i only saw the first episode but it went into detail about the elaborate process they went through to make sure the manufacturers of the drug didnt know which shots would kill you. and the main character worked for an agency that had to tell the people and their family that the person was going to die 24 hours before hand and offer grief counseling to them. this one boy went all crazy and killed the people who were picking on him and the main character tried to get him to stop so he didnt dishonor his family. i think the main character had a bunch of inner monologues about his job and how he thought it was necessary but he hated it i think. any who if you know it, help me out! thanks!
