[Identify] Hentai manga about terminally ill guy hunting girls

Hi everyone!

I was hoping someone could help me identify a hentai manga I remember reading, but I cant remember the title.

The story starts with a guy in a doctors office, and the doctor tells him that hes sick and has like a month left to live. So the guy goes out and decides that if hes gunna die, he might as well fuck as many girls as he can. The last girl I think is an american loli (maybe all the girls are lolis), and the story ends with the doctor calling the guy back, and telling him that hes actually not sick.

Thanks in advance

Found it. Its called Final Half Year, by kumoi yama.
