Since Taemin's real body died, he was likely cremated as a pauper, unless Woojin's family paid for some funeral at Woojin's request.
Do what I do: imagine the real SiWon reborn into a kind, loving, understanding, rich family and he has a wonderful, happy life with good siblings and a great mate and a great career and no suffering.

I mean... I have tons of questions like how the seme is in the hospital when taemin is about to die? or if he knows where taemin is why didn't he show up and meet him? what happen to taemin's real body?
