Mostly it will be Like that Ye, cause when Shin so ri got knocked out she was back as Kang Dan sim so she needs to throw out somehow kangs Soul back to the past and she can live longer as the real Shin so ri :3

tbh it Looks more Like Shin so ri did time Travel the First time back to the joseon when she was in the car accident and Forgot about the past. This would make sense cause Shin so ri is remebering her time as a Child but doesnt remeber her time when she was a Teenager. And kang when she was in the River Almost died too. She did time Travel to the Future and lived as Shin so ri. the reason Shin so ri did Return to her Body is because Kang is dying and she needs to Return fast back to her Original Body otherwise she will Stuck in the past. other reason i think Like This is because Shin so ri was always a good actor and as a kid her Acting skills were really good. while kang in her past was more a passive Person and quite shy . so when Shin so ri did time Travel it would make Sense Why After her Childhood she was so Bad at Acting. it was Bad because kang Never was a good actor Like the real Shin so ri. ye thats the Plot that i think is Happen . Shin so ri did Return from the past and did Not time Travel at the First Place

what the shamen means is that Kang needs to Return back from the Future to the past and Shin so ri needs to Return as kang the concubine back to Shin so ri. Cause when kang real Body dies and Shin so ri is Not in her own Body Then she will die as kang dan sim
