Spring Turns to Spring

Get Here, Bom Sam! (1x5)

:

The two spring-named ladies, Bo Mi and Bom, switch into each other’s bodies again, and this time they march out to find the cause. They go to a hospital to get an MRI but nothing, in particular, is found. On their way back out, they see Bom Sam. At a split second, Bo Mi realizes that he’s been at the scene every time their body-swapped and dashes to catch him.
