That theory doesn't make much sense. In both parts, Naksu was the one who fully controlled the body. Buyeons body…
if jby were to get her body back, he'd fall out of love. He's in love with naksus soul, not with whatever body she's in. for example In their most recent kiss scene he kissed her eyes. Her eyes are naksus soul. I get what you are trying to say but it doesn't make sense.
Uk and Naksu didn't fall in love at first sight this season. Their souls knew each other, their feelings never changed, they were in love all the time.

He doesn't need to know how naksu looks like so i dont really understand ur point. Uk fell in love with naksus soul (once again) one reason is because uk saw naksu in JBY. He might have thought that JBY actually WAS JBY, but it wasn't and everyone can see how much JBY is like Naksu, because they still have the same personality.
