I remeber seeing a anime/manga trailer a long time ago and from what I can remeber this guy who had been living for a shit ton of years but looked like he was like 25 gave all his minutes of life which you have to pay for, to another random poor guy and tells him to do some good with him, then the guy who lived a shit ton kills himself. This could be a movie instead of a manga/anime but I'm pretty sure its a manga/anime thx in advance
