Seme yakuza boss has always had a weak body always sick and was always told he wouldn’t live long. He got another prognosis that he’d die in 3 years. His subordinate (Uke) is the one he cares for and is struggling to tell him. He eventually works the courage after a night together and Uke brushed it off and talked him down.
Very short was okay.
