SPOILER!!!!!
... I mean it! SPOILER!
I don't know where the reincarnation thing comes from. If you know, please tell me. As far as I understood, he ist just reminded of his love for his lover by his feelings for Jin.
And the following SPOILER might put a damper in the mood (sorry),
SO DON'T READ IF YOU DON'T WANT THAT:
Jin seems to only fall in love with Aaron because he does not remember Joon. The moment he gets his memory back, he abandons an unconscious Aaron to look for Joon.
And Aaron knowingly exploits the fact that Jin does not remember anything to get himself laid.
SPOILER
My curious ass had to see some raw and I saw that the doctor and the policeman (brown haired) are together, if I’m not wrong the policeman is a reincarnation of the doctors ex lover in another life. (Don’t if I’m right) ヾ(❀╹◡╹)ノ~
